CCS/AWR1642: AWR1642:the rangeresolution problem of awr1642

Tool/software: Code Composer Studio

Hi:

I am trying using the awr1642 demo mmw project. the rangeresolution is calculated as following

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);

I do not konw where ((3.6*1e3*900)/(1U << 26)) come from.
