[参考译文] IWR1843：MRR 例程 RX 端口校准参数

https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1242079/iwr1843-mrr-routine-rx-port-calibration-parameters

大家好、

在 radar_toolbox_1_00_01_07中测试 medium_range_radar 演示时会出现一些问题：

1) dss_main.c 文件中的 void rxGainPhasePARAM_Init (MwDemo_dss_DataPathObj* obj)函数配置接收通道的校准参数，其中是 MRR 和 USRR 的校准参数。 这些校准参数是如何获得的？  

void rxGainPhaseParam_Init(MmwDemo_DSS_DataPathObj* obj)
{
int32_t indx = 0;
if (obj->processingPath == MAX_VEL_ENH_PROCESSING)
{

obj->rxChPhaseComp[indx].imag = 5863;
obj->rxChPhaseComp[indx].real = 19158;indx++;

obj->rxChPhaseComp[indx].imag = 2858;
obj->rxChPhaseComp[indx].real = 23451;indx++;

obj->rxChPhaseComp[indx].imag = 4569;
obj->rxChPhaseComp[indx].real = 22093;indx++;

obj->rxChPhaseComp[indx].imag = 0;
obj->rxChPhaseComp[indx].real = 16399;indx++;
}
else if (obj->processingPath == POINT_CLOUD_PROCESSING)
{


obj->rxChPhaseComp[indx].imag = 21646;
obj->rxChPhaseComp[indx].real = 7035;indx++;

obj->rxChPhaseComp[indx].imag = 21172;
obj->rxChPhaseComp[indx].real = 18420;indx++;

obj->rxChPhaseComp[indx].imag = 15490;
obj->rxChPhaseComp[indx].real = 21080;indx++;

obj->rxChPhaseComp[indx].imag = -3905;
obj->rxChPhaseComp[indx].real = 25130;indx++;


obj->rxChPhaseComp[indx].imag = 0;
obj->rxChPhaseComp[indx].real = 16399;indx++;

obj->rxChPhaseComp[indx].imag = -7985;
obj->rxChPhaseComp[indx].real = 18443;indx++;

obj->rxChPhaseComp[indx].imag = -10962;
obj->rxChPhaseComp[indx].real = 15291;indx++;


obj->rxChPhaseComp[indx].imag =-17653;
obj->rxChPhaseComp[indx].real = 3133;indx++;

obj->rxChPhaseComp[indx].imag = 386;
obj->rxChPhaseComp[indx].real = -17208;indx++;

obj->rxChPhaseComp[indx].imag = 8587;
obj->rxChPhaseComp[indx].real = -18744;indx++;

obj->rxChPhaseComp[indx].imag = 11857;
obj->rxChPhaseComp[indx].real = -15772;indx++;

obj->rxChPhaseComp[indx].imag = 18493;
obj->rxChPhaseComp[indx].real = -2907;indx++;

}
}

2) 使用 SDK 中开箱即用例程的校准配置文件 profile_calibration.cfg、可以获得以下数据、如何将其转换为 Q15格式、以将其配置为 MRR 例程的校准功能？  

CompRangeBiasAndRxChanPhase 0.1827784 -0.32687 -0.51871 -0.60535 -0.55856 -0.42178 -0.75253 -0.20648 -0.68051 0.28970 -0.67130 0.15488 -0.96405 0.44168 -0.89716 0.52817 -0.63138 0.35147 -0.64502  

3) 3) MRR 为1TX/4RX 操作、profile_calibration.cfg 配置文件为3TX、4RX。 是否可以将其配置为1TX、4RX、然后输出校准参数？

您能帮助检查这个问题吗？ 谢谢。
