AWRL1432: Increasing the range accuray in the demo Level_Sensing

Tool/software:

Hi，

  In the demo  Level_Sensing , the parameter rangeStep (range step (meters/bin)) is about 7cm acoording to the following foemula:

gMmwMssMCB.measureRxChannelBiasParams.rangeStep = (MMWDEMO_RFPARSER_SPEED_OF_LIGHT_IN_METERS_PER_SEC * (gMmwMssMCB.adcSamplingRate * 1.e6)) /(2.f * slope * (2*gMmwMssMCB.numRangeBins));

Now if we want to set  rangeStep as 1cm or 0.5cm, what parameters should be  modified?  I think that if  set numRangeBins larger value, the computation cost will increased and more ram space will be needed. Except increasing the numRangeBins value, is there any other method to improve accuray?

Thanks,

BR,
