AWR6843AOP: 侧装时3D people counting demo 中,到底使用哪八根天线测水平角,且逆矩阵维度和nRxAnt为何为4呢?请求解答

Part Number: AWR6843AOP


你好,请问在6843AOPEVM平台下,3D people counting demo中,CaponBF2D模块中,C:\TI\mmwave_industrial_toolbox_4_11_0\labs\common\src\dpu\capon3d\modules\DoA\CaponBF2D\src,其中raHeatmap()函数中(雷达采用侧装),测量水平方位角时,即做第一次Capon波束形成时,文档中写的是使用了八根天线,但是在程序中,nRxAnt为4,且逆矩阵维度为4*4,但是导向矢量却为8*1的,且导向矢量后面四个元素未使用。请问这难道不矛盾吗?还有请问侧装时,第一次CaponBF,用的是哪八根天线呢?各位能帮我解答一下吗?
