上一期我们用MATLAB对加窗后的距离维数据进行了FFT处理看到了目标和目标距离，这一期我们看看C代码是如何做FFT的，回顾一下1D处理的函数代码：
/*** @b Description* @n* Interchirp processing. It is executed per chirp event, after ADC* buffer is filled with chirp samples.** @retval*Not Applicable.*/void MmwDemo_interChirpProcessing(MmwDemo_DSS_DataPathObj *obj, uint8_t chirpPingPongId){uint32_t antIndx, waitingTime;volatile uint32_t startTime;volatile uint32_t startTime1;MmwDemo_DSS_dataPathContext_t *context = obj->context;waitingTime = 0;startTime = Cycleprofiler_getTimeStamp();/* Kick off DMA to fetch data from ADC buffer for first channel */EDMA_startDmaTransfer(context->edmaHandle[MMW_DATA_PATH_EDMA_INSTANCE],MMW_EDMA_CH_1D_IN_PING);/* 1d fft for first antenna, followed by kicking off the DMA of fft output */for (antIndx = 0; antIndx < obj-&
