- Range = (RangeHValue*256 + RangeLValue)*0.01
- Azimuth = AzimuthValue*2 – 90
- RollCount = RollCountValue
- Verl = (VrelHValue*256 + VrelLValue) *0.05-35
- SNR = Value-127
The reflection Radar-Cross Section (RCS), the target range (Range), the target velocity (Verl),
the target azimuth (Azimuth), and the Signal Noise Ratio (SNR) can be obtained by these
calculations, therefore to accurately detect the target.
Note:
The target speed is the relative movement velocity. When the target is close to the radar sensor,
the target speed value (Verl) is negative; when the target is far away from the radar sensor, the
target speed value (Verl) is a positive number.
6 Data parsing examples
Take Message ID as the target output information (Target Info) as an example, there is a frame
of the Target Info data message as follows:
Message ID:
0x28TC
Data Payload:
0x01 0xC8 0x07 0xD0 0x32 0x02 0xEE 0x96
Interpretation
：
Message ID = 0x28TC
Data Payload = 0x01 0xC8 0x07 0xD0 0x32 0x02 0xEE 0x96
Each field of Data Payload is parsed as following
：
Index = 1
Rcs = 0xC8*0.5 – 50 = 50
Range = (0x07*0x100 +0xD0)*0.01 = 20
Azimuth = 0x32*2-90 = 10 Rsvd1 = 0
RollCount = (0x0 & 0xE0) >> 5 = 0
Verl = (0x02*0x100 + 0xEE) *0.05-35 = 2.5
SNR = 0x96 – 127 = 23
