quick-start guide
The quick-start guide gives you a guidence to set-up the iSYS-4001 quickly in your application.
A more detailed instruction is given in the GUI - description that is available @ www.innosent.de.

quick start
Install the iSYS-4001 GUI software as described in the document „GUI Interface“ and connect the sensor to your computer.
If you use the iSYS-4001 the first time InnoSenT recommends to use one of the available configuration files to set up the
sensor.
The DEFAULT setting of the sensor when powered up for the first time is the „Short Range“ configuration.
The following configuration files are available @ www.InnoSenT.de (Services -> Downloads)
• Short Range.ipf (for short range applications up to 50m)
• Long Range.ipf (for long range applications up to 150m)
• Demonstrator.ipf (for testing the sensor in house)
Examples how to mount the sensor and the expected detection fields are given on the next pages.

short-range configuration
Load the file „Short Range.ipf“ in the iSYS-4001 GUI and mount the sensor as described in the following:
• mounting height: 2.2m
• mounting angle: 30° - 45° - 60° (depending on your application)
In the short Range configuratoin the ambiguity range is set to 50m.
Typical detection fields for a person are shown beside.
This configuration is supposed to use in applications like:

• mounting height: 1.1m
• mounting angle: 90°
In the „Long Range“ configuratoin the ambiguity range is set to 150m.

detection fields
Providing the width of the antenna in degrees just says, that the transmitted or received energy has dropped at this
point down to 50 percent of the maximum value (3dB-beamwidth). It does definitely not mean that beyond that point no
transmission or reception is possible.
On the right side you see some examples of different detection fields depending on the mounting height and based on the
3dB-antenna-parameters of the iSYS-4001.
The color gradient shows the energy density of the antenna field.The darker the red the higher is the energy density of the
antenna. That means that a small object (e.g. a cat) will be detected later than the border of the ellipse shows, whereat big
objects (e.g. a car) are detected sooner. This is depending on the RCS of the object and is described in the next section.

In the side view you see, that the energy density in the right area of the antenna beams decreases if the mounting angle
of the module rises. Therefore the detection field gets broader, but because of the lower energy the same object has to
move further into the beam @60° mounting angle as @30°.

detection range depending on RCS
The amount of power that is reflected back to the radar depends largely on a quantity called the radar cross section (RCS).
The power reflected by the target can be much stronger in some directions than in others. As a result, that reflected power
will be much greater or much smaller than the isotropic power depending on how the target is oriented to the transmitting
radar. Although RCS is technically an area and typically expressed in square meters (m2).
The RCS of an object is depending on its geometric cross section (the geometric cross section refers to the area the target
presents to the radar, or its projected area); Reflectivity (Reflectivity refers to the fraction of the intercepted power that is
reflected by the target, regardless of direction) and its Directivity (Directivity is related to reflectivity but refers to the power
scattered back in the direction of the transmitting radar).
Therfore the maximum detection distance of different objects is strongly depending on its RCS as well as on their
orientation to the sensor and can strongly differ for different objects.

ambiguity range
If you install the iSYS-4001 in your application you have to think about the ambiguity range of the sensor. The ambiguity
range is the distance within the sensor provides correct measurements. In case of the iSYS-4001 the ambiguity range can
be selected. Two distance ranges are available: 0m to 50m and 0m to 150m. Select the proper distance range depending
on your application. The ambiguity range is the distance within the object will be calculated correctly. If an object is
detected outside of the selected ambiguity range (e.g. a large truck), this object will be mirrored back into the ambiguity
range.
Example: ambiguity range 50m
object in a distance of 25m will be calculated at 25m
object in a distance of 52m will be calculated at 2m
object in a distance of 132m will be calculated at 32m
Finally you can only avoid this effect by installing the sensor in this way, that no reflections of objects outside of the
selected ambiguity range can occur.

10m0m 20m 30m 40m 50m 60m 70m
10m0m 20m
detection at 60m results in a calculation distance of the object at 10m

80m
80m
object is detected within the ambiguity range of 50m
distance calculation is correct
object is detected outisde the ambiguity range of 50m
object will be mirrored inside the ambiguity range
distance calculation is not correct
to overcome this effect, install the sensor in this way
that the antenna pattern can not illuminate the
area outside of the ambiguity range

FSK modulation
The FSK modulation enables the possibility to detect speed and distance of moving objects. The FSK modulation is the
standard mode of the iSYS-4001. Within this mode different speed and distance limits can be set.
IMPORTANT: - with the FSK modulation there is no possibility to detect stationary objects.
- the distance to more than one object can only be determined if the objects differs in speed. If not a
distance that is between the detected objects will given back by the system.
