2Basic radar Doppler concepts
The main radar technique used for this demonstration is Continuous Wave (CW/Doppler) radar.
Doppler radar operates on the principle of sending a beam of electromagnetic radiation waves, tuned to a
precise frequency, toward a moving object. When the electromagnetic radiation wave hits the moving object, it
“bounces” back toward the source, which also contains a receiver. However, since the wave is reflected off a
moving object, the wave is shifted as outlined by the Doppler effect.
The wave that is coming back toward the radar is treated as an entirely new wave, as if it were emitted by the
target it bounced off. The target is acting like a new source for this new wave. When it is received at the radar,
this wave has a frequency different from the frequency that was originally sent toward the target.
Radar transceiver Low frequency Doppler signal
Amplitude depends on reflectivity and distance.
Figure 1 Doppler effect
Since the electromagnetic radiation was at a precise frequency when sent out and is at a new frequency on its
return, this can be used to calculate the velocity 𝑣of the target.
The change in phase between the transmitted and received signal is used to calculate the target’s velocity. The
Doppler effect shifts the received frequency up or down based on the radial velocity of the target (closing or
opening) in the beam, allowing for the direct and highly accurate measurement of target velocity.

control resides in the main loop, where two possible events can trigger further processing:
frame timer interrupt
GUI request by the host communication protocol.

Device initialization –this is the first task to be executed, onlyonce when the firmware is started. During
this task, the firmware initializes XMC™ peripherals and the Sense2GoL Pulse radar device, then registers
the used endpoints for the host communication. Program control then goes to the main loop.
Frame timer interrupt –this is a periodic hardware timer interrupt, which triggers the start of the new
frame raw data acquisition process.
Raw data acquisition –the BSP layer is configured to start collecting raw data from the radar device.
Radar algorithm –once raw data is collected, run the registered algorithm process in order to compute
the parameter of the target’s velocity.

4.4.1 Doppler pulse generation
Pulse generation is the first part of the data acquisition process. It is triggered by an internal frame timer, which
will start generating pulses. The Sense2GoL Pulse firmware communicates and controls the BGT and S&H over
PWM signals. It generates periodic and continuous pulses based on the number of data samples required.
As shown in 15 and Table 1, the BGT24LTR11 Shield is controlled through three PWM signals and one normal
GPIO signal.
PWM1 and PWM2: PWM control signals for BGT_VCC and BGT_TX_ON, they are used to turn on the
BGT24LTR11 only during the “Pulse” duration and it remains off for the remaining time.
PWM3: Normal GPIO control signal for BGT_VCC_PTAT, it is used to turn on the VPTAT 1 ms before the
start of the first pulse of the frame and then remains on until the end of the frame time.
S&H_EN: PWM control signal for S&H, it is used to turn on the S&H only during the “Pulse” duration and
it remains off for the remaining time.

The pulse width or BGT VCC on-time can vary between 1 and 10 µs, and it represent the time portion to have one
data sample. Short pulse width reduces the sample time of the BGT’s output signals, hence saving more power.
However, the time might not be enough to charge to the S&H, reducing the final signal strength at the output.

4.4.2 Data sampling
The data acquisition process for Sense2GoL Pulse application is shown in Figure 13.
The start of the data acquisition process will be triggered by an internal frame timer, which will start pulse
generation over PWM signals. The data sampling process is triggered by an internal PWM signal at the same time,
which triggers the ADC to start sampling data from the RX antenna.
Once an ADCsample is ready to be moved to the acquisition buffer, the DMA transfer starts. This taskis repetitive;
it will end once the number of required samples per frame is reached. At that moment, the DMA will stop the
transfer process by raising a transfer complete interrupt.
The frame size (or number of samples per frame) depends on the number sample required by the application or
the algorithm and the sample skip count. The sample skip count is the number of samples to be skipped in each
frame to get rid of the DC offset in the I and Q signals. The recommended sample skip count value is 100; these
samples are completely disregarded in the signal processing chain.

of the acquisition process:
Step 1 –configure and enable DMA: DMA source/destination address set-up; four DMA channels are
configured for the RX complex (I/Q) data samples (Q1 HG, I1 HG, Q1 LG and I1 LG).
Step 2 –configure pulse generation: Configure all PWM control signals for BGT and S&H.
Step 3 –trigger pulse generation:Triggered by an internal frame timer at the beginning of each frame;
start PWM pulse generation and ADC data sampling.
Step 4 –start ADC sampling:ADC sampling will start automatically at the same time as pulse generation; it
is controlled by an internal PWM signal in order to trigger equidistant ADC samples.
Step 5 –stop acquisition process:Based on the number of samples required, disables the DMA peripheral
and stops pulse generation and ADC sampling.

4.5 Radar control layer
The Sense2GoL Pulse software package provides a simple interface to the radar kit through the radar control
layer, which offers full flexibility to configure all radar parameters based on the application end requirements.
4.5.1 Radar control API
The APIs define the high-level interface used to configure the radar RF parameters, the behavior and
capabilities of the component, and its inputs and outputs, and provide a set of firmware methods to manage
radar functionalities. Radar control APIs are called from the application layer and are prefixed by “radar_”.
Detailed technical information about the radar APIs available to the user is provided in a compiled HTML file in
the Firmware_Software/Documentation/FW_API folder, where all the functions and parameters are described.
4.5.2 Data store module
The data store module is apart from the radar control layer; it mainly contains the hardware device settings
and the algorithm settings structures, as shown in Figure 14.

Sense2GoL Pulse (Pulsed Doppler) Software User Manual
24 GHz-based radar applications
Firmware description
Figure 14 Data store hardware device and algorithm settings structures
These two structures are shared between all firmware modules. If a firmware module, e.g. the host
communication library or algorithm, requires one or more parameters from the settings structures, a fetch
operation is performed to get the up-to-date value from the data store, as shown in Figure 15. The resulting
structure holds the results of the last algo operation.
On the other hand, if there is an update for one or many parameters in the settings structures, a push/store
operation is performed to update the data store structures with the new changed value.
A shadow (or a copy) of the hardware settings structure is maintained in the data store, and it always contains
the old settings parameters. In case of unsupported parameters (e.g. the value is out of range), the current
hardware structure is discarded and overwritten by the shadow copy and the new required change will be
discarded.
At the beginning, the shadow and current settings structures parameters are set to the default settings values
from the config.h file. The user can change these default settings by updating the config.h file or through the
radar GUI tool interface.
In case of a valid hardware change request received from the GUI, the hardware structure will be updated with
the new value in the data store. The radar control sub-module will apply this change on the BSP driver before
the start of acquisition of the next new frame.

In Sense2GoL Pulse firmware, the EEPROM is used to store the hardware settings and the algorithm settings
structures as shown in Figure 14. In addition to that the EEPROM contains a unique, pre-defined and pre-
programmed string ID, which is used to identify the BGT24LTR11 Shield board.
When the Radar Baseboard XMC4700 boots up, the firmware detects if a radar shield is plugged into the
connectors. If the radar shield is plugged in correctly, it reads the information in the EEPROM’s memory to
determine what kind of shield is plugged into the interface. The power supply of the radar shield is only
enabled when the shield is correctly identified.

After that, the firmware reads the hardware and the algorithm settings from EEPROM. In case of valid settings
the firmware will start based on these new settings; otherwise it will start with the default settings and
