在毫米波工业工具箱3.2中traffic_monitoring_16xx这个demo,实地测量的时候会出现点云跳变,查看技术文档,可能需要校准参数,以获得最佳性能,请问这部分校准应该怎么操作呢?有详细步骤吗?
We strongly recommend user to calibrate the EVM using procedure described in section “Range Bias and Rx Channel Gain/Offset Measurement and Compensation” in mmwave SDK OOB demo document in
(<SDK_INSTALL_PATH>/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html).

“Range Bias and Rx Channel Gain/Offset Measurement and Compensation”这个文档中第一步Set a strong target like corner reflector at the distance of X meter (X less than 50 cm is not recommended) at boresight.是要买一个角反射器做实验吗?有点不懂

是的,需要买个角反器。
下面帖子讨论了一些基本概念,可以参考一下。https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1032537/iwr6843isk-ods-questions-about-the-range-bias-and-rx-channel-gain-phase-measurement-and-compensation
