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_tnegativeBinIdx; //值为-5/*! @brief maximum positive range bin (1D FFT index) to be compensated */int16_tpositiveBinIdx; //值为8
