TI单芯片毫米波雷达代码走读（十三）—— 多普勒维（2D）处理之核心函数

今天我们来看看2D处理的核心函数：void MmwDemo_interFrameProcessing(MmwDemo_DSS_DataPathObj *obj)，代码如下，先大致浏览一下。

/**
 *  @b Description
 *  @n
 *    Interframe processing. It is called from MmwDemo_dssDataPathProcessEvents
 *    after all chirps of the frame have been received and 1D FFT processing on them
 *    has been completed.
 *
 *  @retval
 *      Not Applicable.
