AWR1243: AWR1243 range-azimuth heat map problem

In MIMO mode, the SDK and matlab scripts (radar_cascade_demo.m) are default parameters.

This is the range profile:

The corresponding distance should be about 2.7 meters (close to the actual distance).

This is the range-azimuth heat map:

The distance shown is about 5.4 meters, twice the actual distance.

Here's another one:

The corresponding distance should be about 5.3 meters.

It's also twice the actual distance.

This is the only part of the matlab code that I've changed:

How should I modify the code to make the range azimuth heat map appear correctly?

Thank you very much,
