AWR1843: 中距离雷达 测高 原理

BING NIE
Prodigy 160 points
Part Number: AWR1843


        peakAzimIm = (float) obj->azimuthOut[azimIdx].imag;
        peakAzimRe = (float) obj->azimuthOut[azimIdx].real;

        peakElevIm = (float) obj->elevationOut[azimIdx].imag;
        peakElevRe = (float) obj->elevationOut[azimIdx].real;
   
    tempIm = (peakAzimIm * peakElevRe) - (peakAzimRe * peakElevIm);
    tempRe = (peakAzimRe * peakElevRe) + (peakAzimIm * peakElevIm);
   
    Wz = (float) atan2sp(tempIm, tempRe) * (1.0f/PI_) ;
        if (Wz > 1)
        {
            Wz = Wz - 2;
        }
        else if (Wz < -1)
        {
            Wz = Wz + 2;
        }
        z = range * Wz;    
请问MRR demo中代码测高的原理是什么？谢谢！
