Hello, TI technicians：
I have a question about the MIMO data processing of the TI cascade board （AWR2243 cascade ）：
I use awr2243 cascaded RF + DSP EVM board and mmwave studio to collect data. Fig. 1 is the processing result of Matlab processor in Matlab example provided in mmwave studio.
There are two stationary targets in the scene and no moving targets。 However, from the result, the moving target information will be diffused at the static target in the processing result, as shown in the first and second pictures in Fig. 1. However, from the results, a lot of Doppler interference information is presented around the stationary target, such as the first and second pictures in Fig. 1. And with the increase of target reflection power, this phenomenon becomes more and more obvious.

What is the reason for this phenomenon? Which part of the board may have a problem? How should it be solved? I hope you can give me an answer。
