Other Parts Discussed in Thread: MMWCAS-DSP-EVM, AWR2243, AWR1243,
Sir/Madam,
I am trying to develop a Cascaded Radar Solution based on TIDEP01012 & TIDEP01017.
For that I built PROCESSOR_SDK_RADAR_03_08_00_00, from source and deployed it to my MMWCAS-DSP-EVM.
**Changes I made while building the sdk**
1. Set the MAKECONFIG=tda2xx_cascade_bios_radar
2. Applied the patches listed in the following thread. (According to our understanding these changes are necessary to make the SDK compatible with AWR2243 chip based RF board)
**Test Setup and Example usecase**
We installed the radar at a height of 3m above the ground and ran usecase a: Cascade Radar (4 AWR1243) Capture + Radar Object Detect (DSP) + NetworkTx (TDA2xx Only) out of the following available usecases
[IPU1-0] 9: Cascade Radar (4 AWR1243) Capture + Null (TDA2xx Only)
[IPU1-0] a: Cascade Radar (4 AWR1243) Capture + Radar Object Detect (DSP) + NetworkTx (TDA2xx Only)
[IPU1-0] b: Cascade Radar (4 AWR1243) Capture + FFT (EVE) + Tx Beam Form Static Map (DSP) + NetworkTx (TDA2xx Only)
For subsequent options we choose the following settings
1. 2D FFT Core Selection: DSP; //Available options DSP, EVE
2. Select Network Mode: TFTDP //Available options TFTDP, TCP/IP
**Output**
The radar is not able to detect objects beyond 3 m.
**LOGS**

**QUESTIONS/ OBSERVATIONS**
1. My RF-Board contains some sort of dark patches on and around the antenna patch area (image attatched below). Is it norrmal ? Does it have anything related to the poor performace I am getting ?
2. Also I noticed my range to slightly increase if I play with Control Calibration Settings and Control Peak Detection Settings
Paramters for Control Calibration,
<numFrames> ,<rangeStartBin>,<rangeEndBin>

May I know the default calibration values that should work for MIMO or the relevant documentation that can help me understand these settings. As the SDK was made for AWR1243, do I need to change any defaullt CFAR/Control Calibration settings to make it compatible with AWR2243.
