MMWCAS-RF-EVM: Questions about the radar sensor in the detection range, especially in the case of small RCS (human body)

Part Number: MMWCAS-RF-EVM
Other Parts Discussed in Thread: MMWCAS-DSP-EVM, , AWR1243

The used evaluation board: MMWCAS-RF-EVM, MMWCAS-DSP-EVM

The used sortware: mmWave_Studio (latest version)

Radar operating mode: MIMO

We are very pleased to see that the EVM work, but we also found some issues. We saw that this radar EVM could detect a human body at a distance of 150 meters in the user's guide. But we found that it could only detect a human body at a distance of 50 meters in our actual tests, whether setting chirp parameter to LLR mode or MRR mode.

Is there any way to detect humans at greater distances in MIMO mode?

We saw that the AWR1243 sensor has a maximum transmission power of 12dBm.Then what is the maximum transmission power of AWR1243P on MMWCAS-RF-EVM. Is there any way to increase its transmission power?
