Part Number: IWR6843ISK
Tool/software: Code Composer Studio
Hi，
nowadays， we use IWR6843 as a sensor to detect static object ，the signal process flow： ADC data -> range fft -> doppler fft , cfar along doppler dimension， then cfar along range dimension，get object's range index and doppler index，a dbf algorithm to get object’s azimuth angle，the object were detected from zero doppler，ground clutter is also detected，we find that static object’s position is fixed， but groud clutter's position random change in a region，a large cfar threshold, some object can't be detected, a small cfar threshold, many ground clutter points are deteced，we have done a lot of work to eliminate clutter，but the effect is not good.
How to make a distinction between ground clutter and static object ？？？
