Tool/software:
Hi Ti's experts,
We encountered detMatrix data anomalies during the development process. Please help us analyze the possible causes.
Board : AWRL6432
SDK Version: MMWAVE_L_SDK_05_05_02_00
DopplerBin : 32
RangeBin: 64
DetMatrix[32*64]
Actual Results：
We have two radars working at the same time in a car with exactly the same configuration, we will encounter detMatrix data anomalies and the overall dematrix data will be too large than normal frame. The high-speed area is very large,The bright bar in the picture appears
Expected Results:
In a scene with only slight movement, the energy in the high-speed area should be very low and the color should be blue(low energy). The yellow bright bar in the picture below should not appear
Note:
The X-axis represents the number of frames. There may be N frames in a scene data.
The Y-axis in the left figure has 32 velocity units, and the sum of all detMatrix energies of the same velocity unit. .
The Y-axis in the right figure has 64 range units, which is the sum of all detMatrix energies in the same range unit.
We want to know under what circumstances will cause this abnormal data?
The test is about 50 frames per time, and this phenomenon may occur about 10 times out of 100 tests，Rate is 10/5000frames.
The frame period is stable and the distance between the two radars exceeds 1 meter.
Normal Scene Data:
