TI单芯片毫米波雷达代码走读（十一）—— 距离维（1D）处理之直流去除

chirp内处理void MmwDemo_interChirpProcessing()函数最后有这样两行代码：

    if(obj->cliCfg->calibDcRangeSigCfg.enabled)
    {
        MmwDemo_dcRangeSignatureCompensation(obj, chirpPingPongId);
    }

我们首先抓了下cliCfg结构体内的数据，数据可通过关注公众号“星巡社”下载（右下角有下载按钮），然后我们关注的结构体calibDcRangeSigCfg内部的变量如下：

 /**
 * @brief
 *  Millimeter Wave Demo DC range signature compensation
 *
 * @details
 *  The structure contains the DC range antenna signature removeal configuration used in data path
 */
typedef struct MmwDemo_CalibDcRangeSigCfg_t
{
    /*! @brief    enabled flag:  1-enabled 0-disabled */
    uint16_t    enabled;

    /*! @brief    maximum negative range bin (1D FFT index) to be compensated */
    int16_t     negativeBinIdx;    //值为-5

    /*! @brief    maximum positive range bin (1D FFT index) to be compensated */
    int16_t     positiveBinIdx;    //值为8

    /*! @brief    number of chirps in the averaging phase */
