MMWCAS-DSP-EVM: Side effects of changing the value of azimuthFFTnums for "4 AWR1243 Capture + Radar Object Detect (DSP) (MIMO) + NULL"

Hello,

Currently, I'm developing a radar using a custom RF board.
The custom board uses all transmitting antennas (12Tx), with 6 elevation virtual antennas and 32 horizontal virtual antennas.

The following contents have been revised with reference to past Q & A.


① Antenna arrangement
Path: C: \ PROCESSOR_SDK_RADAR_03_08_00_00 \ vision_sdk \ apps \ src \ rtos \ radar \ src \ usecases \ cascade_radar_object_detect \ chains_cascadeRadarOd.c
Contents:
1. Tx antenna placement setting
Chanis_RadarAntOffset gCascadeRadarTxAntArray [CHAINS_RADAR_CASCADE_NUMSENSORS] [CHAINS_RADAR_CASCADE_MAX_TX_ANTENNA_PERSENSOR]
2. Rx antenna placement setting
Void Chains_cascadeRadarFillRxAntennaOffsets (aoa_rxAntOffset_t * aoa_sensorRxOffset)

② Chirp setting
Path: C: \ PROCESSOR_SDK_RADAR_03_08_00_00 \ vision_sdk \ apps \ src \ rtos \ radar \ src \ common \ chains_common_cascade_ar12xx_config_mimo.c
Contents:
1. Setting the number of Tx
/ * Total number of Txs across sensors that are chirped as part of TDM-MIMO * /
/ * #define CHAINS_CASCADE_RADAR_NUM_TX_ANTENNA (8U) * /
#define CHAINS_CASCADE_RADAR_NUM_TX_ANTENNA (12U) / *** 20220407 *** /
2. Setting the number of chirps

/ * #define CHAINS_CASCADE_CHIRP_END_IDX 9 * /
#define CHAINS_CASCADE_CHIRP_END_IDX 11 / *** 20220407 *** /
3. Chirp settings

③ Change the number of executions of azimuth FFT

Contents:
#define ALG_FXN_RADAR_DSP_PROCESS_AOA_MAX_AZIMUTH_FFT (6U) / * 20220413 change (4U → 6U) * /

path:

Contents:
aoaCreateParams-> numAzimuthFFTs = 6; / * 20220413 change (4 → 6) * /

However, when I execute it, there is a problem that the point cloud is not displayed.
After debugging, I found that when I set "aoaCreateParams-> numAzimuthFFTs = 6", the azimuthFFT size should be 256, but it becomes 12, and numAzimDetPeaks becomes 0.

Could you help me solve this problem?

Thank you very much for the help.

best regards,
