Binocular Vision and Phased Array Radar (Detection and Obstacle
Avoidance System)
Prole
The aircraft is equipped with the phased array radar system and binocular vision system. The
systems provide multidirectional obstacle sensing[1] as well as terrain follow and bypass functions to
ensure flight safety. In an optimal operating environment, the radar module can help the aircraft to
fly above the vegetation at a constant distance and ensure even spraying and terrain following. In
addition, the flight control system limits the descent speed of the aircraft according to the distance
between the aircraft and ground detected by the radar module to achieve a smooth landing.
The binocular vision system is enabled automatically when the aircraft is in use. In Route and A-B
Route operation modes, users can enable the terrain follow and bypassing functions for different
terrain types. The aircraft will fly above the vegetation at a constant spraying distance and bypass
detected obstacles. In Manual and Fruit Tree operation modes, the radar can measure the spraying
distance above the vegetation or other surfaces. Obstacle avoidance can be used in any mode.
[1] The downward sensing system is used to assist in Terrain Follow, while the sensing function on the other
sides is for obstacle sensing.
Detection Range of Binocular Vision System and Radars
Binocular vision system: 90° (horizontal), 106° (vertical), 0.5-29 m.
Forward phased array radar: 360° (horizontal), ±45° (vertical), ±45° (upward, cone),1-50 m.
Rear phased array radar: 360° (vertical), ±45° (horizontal), 1-50 m.
Note that the aircraft cannot sense obstacles that are not within its detection range. Fly with
caution.
The effective detection range varies depending on the size and material of the
obstacle. When sensing objects such as buildings that have a radar cross section (RCS)
of more than -5 dBsm, the effective detection range is 50 m. When sensing objects
such as power lines that have a RCS of -10 dBsm, the effective detection range is
approximately 30 m. When sensing objects such as dry tree branches that have a RCS
of -15 dBsm, the effective detection range is approximately 20 m. Obstacle sensing
may be affected or unavailable in areas outside of the effective detection distance.
Fly with caution when the aircraft is near an obstacle that is at a similar altitude with
the bottom of the aircraft. The aircraft cannot detect the obstacle as most or even the
whole obstacle is out of the detection range.
Omnidirectional Obstacle Avoidance Function
Enable the function in Sensor Settings, or tap the radar indicator in Operation View or press the
button on the remote controller to enable obstacle avoidance. When enabled, the aircraft will
enter obstacle avoidance mode when obstacles are detected. Users can control the aircraft to
fly in a direction away from the obstacle according to the prompt in the app. Obstacle avoidance
is used in the following two scenarios:
1. The aircraft begins to decelerate and hovers in place when it detects an obstacle. While
decelerating, users can control the aircraft to fly in a direction away from the obstacle.

AGRAS T50/T25 Unmanned Aircraft Flight Manual
12 ©2023 DJI All Rights Reserved.
2. The aircraft immediately brakes and hovers if it detects an obstacle nearby. Users can fly the
aircraft in a direction away from the obstacle to regain full control of the aircraft.
Obstacle avoidance is disabled during auto landing. Make sure to operate the aircraft
with caution when controlling the aircraft manually during auto landing.
In some scenarios such as with power lines, small obstacles, or objects that are at the
same level as the landing gear, obstacle sensing may be rendered ineffective. Fly with
caution.
Terrain Follow and Bypassing Functions Usage
In Operation View, tap > to enter Sensing Settings, and select the task terrain from the
provided options such as Flatland, Mountains and Hilly Orchards, or Above Water in Sensing
Settings. Altitude stabilization and obstacle bypassing can also be enabled in Sensing Settings.
The aircraft will follow terrain automatically and adjust its altitude during flight based on the set
height above crops, and bypass detected obstacles.
Flatland
This mode is suitable for operations on flatlands or orchard fields without obvious surface
elevation changes. When enabled, the aircraft will attempt to bypass obstacles from the side.
Moving the control stick can pause auto bypassing. The aircraft will hover in place if auto
bypassing fails. Users can manually bypass the obstacle by controlling the aircraft.
Mountains and Hilly Orchards
This mode is suitable for operations on undulating terrain with mountain crops and fruit trees.
When enabled, the aircraft will attempt to bypass obstacles by avoiding them from above.
Moving the control stick can pause auto bypassing. The aircraft will hover in place if auto
bypassing fails. Users can manually bypass the obstacle by controlling the aircraft.
Above Water
This mode is suitable for operations above water. When enabled, the aircraft will attempt to
bypass obstacles from the side. When Altitude Stabilization is enabled, the aircraft will use the
Altitude Relative to Ground (Radar) for terrain following.
The max flight speed of the aircraft will be limited to 10 m/s and the height above
vegetation will be limited from 2.5 m to 8 m when obstacle bypassing is enabled.
Choose the appropriate task terrain settings for the environment. Otherwise, the
aircraft may not be able to keep the set height above crops or fail to bypass obstacles.
For example:
a. When performing operations on flat, open spaces with Mountain and Hilly
Orchards mode enabled, the aircraft will ascend abnormally in some instances
such as when encountering power poles or trees.
b. When performing operations in hilly or mountainous areas with Flatland or Above
Water mode enabled, the aircraft may fail to bypass obstacles from the side and
spraying effectiveness may be adversely affected.
Only altitude stabilization is available in Manual mode. The aircraft will hover in place
after encountering an obstacle instead of automatically bypassing them.

AGRAS T50/T25 Unmanned Aircraft Flight Manual
©2023 DJI All Rights Reserved. 13
When flying at night, in dark areas or the binocular vision sensors are dirty, the
aircraft will use data measured by the radar for terrain following. Fly with caution.
After the additional sprinklers are mounted, the performance of the binocular vision
system may be affected by spray droplets. Fly with caution.
In some scenarios such as with power lines or small obstacles, the bypassing function
may not be able to bypass the obstacle successfully. Users can manually bypass the
obstacle by controlling the aircraft.
Terrain Follow will be affected when the aircraft is flying over water. Fly with caution.
Make sure the relative flight altitude is higher than 2 m to avoid any accidents with
the aircraft.
Radar Usage Notice
DO NOT touch or let your hands or body come in contact with the metal parts of the
radar module when powering on or immediately after flight as they may be hot.
Maintain full control of the aircraft at all times and do not rely completely on the
radar module and DJI Agras app. Keep the aircraft within VLOS at all times. Use your
discretion to operate the aircraft manually to avoid obstacles.
In Manual operation mode, users have complete control of the aircraft. Pay attention
to the flying speed and direction when operating. Be aware of the surrounding
environment and avoid the blind spots of the radar module.
The obstacle avoidance function is disabled in Attitude mode.
When sensing objects such as an inclined line, inclined utility pole, or power line
at an inclined angle against the flying direction of the aircraft, the radar detection
performance will be affected since most of the radar electromagnetic waves are
reflected to other directions. Fly with caution.
The radar module enables the aircraft to maintain a fixed distance from vegetation
only within its working range. Observe the aircraft’s distance from vegetation at all
times.
Operate with extra caution when flying over inclined surfaces. The recommended
maximum inclination at different aircraft speeds are 10° at 1 m/s, 6° at 3 m/s, and 3°
at 5 m/s.
Comply with local radio transmission laws and regulations.
The sensitivity of the radar module may be reduced when operating several aircraft
within a short distance. Operate with caution.
The radar module is a precision instrument. DO NOT squeeze, tap, or hit the radar
module.
Before use, make sure that the radar module is clean and the outer protective cover
is not cracked, chipped, sunken, or misshapen.
Keep the protective cover of the radar module clean. Clean the surface with a soft
damp cloth and air dry before using again.

AGRAS T50/T25 Unmanned Aircraft Flight Manual

Binocular Vision System Usage Notice
The performance of the binocular vision system is affected by light intensity and the
patterns or texture of the surface being flown over. Operate the aircraft with great
caution in the following situations:
a. Flying over monochrome surfaces (e.g., pure black, pure white, pure green).
b. Flying over highly reflective surfaces.
c. Flying over water or transparent surfaces.
d. Flying in an area where the lighting changes frequently or drastically.
e. Flying over extremely dark (< 10 lux) or bright (> 10,000 lux) surfaces.
f. Flying over surfaces with repeating identical patterns or textures or with
particularly sparse patterns or textures.
Keep the cameras of the binocular vision system clean at all times.
Make sure that there are clear patterns and adequate lighting in the surroundings
since the binocular vision system relies on images of the surrounding environment to
obtain displacement data.
The obstacle sensing function of the binocular vision system may not work properly
when the aircraft is operated in a dim environment or over water or surfaces without
a clear pattern.
Keep the cameras of the binocular vision system clean. Make sure that the aircraft is
powered off. First remove any larger pieces of grit or sand then wipe the lens with a
clean, soft cloth to remove dust or other dirt.
