IWR6843: The SDK of IWR6843

Hi all

i see the SDK of ODS of IWR6843, it calcute the distance by the fornula just as below

/*------------------------------------------------------------------------------------------------------------

dataPathObj->rangeResolution = MMWDEMO_SPEED_OF_LIGHT_IN_METERS_PER_SEC *
                profileCfg.digOutSampleRate * 1e3 /
                (2 * (profileCfg.freqSlopeConst) * ((3.6*1e3*900) /
                 (1U << 26)) * 1e12 * dataPathObj->numRangeBins);

profileCfg.freqSlopeConst        = (int16_t)(atof(argv[8]) * (1U << 26) /
                                                 ((gCLI_mmwave_freq_scale_factor * 1e3) * 900.0));

mmwave_freq_scale_factor=2.7

*/------------------------------------------------------------------------------------------------------------

But why do you change the freSlopeConst ?  and what's the meaning of  "mmwave_freq_scale_factor"?

Thanks
