Hi,
TI experts
we use IWR6843ISK to collect ADC data whit 2 Tx and 4 Rx in TDM-MIMO method，form 8 virtual channel，the iwr6843isk's antenna is facing the ceiling in the room，after geting ADC data，analyse data，32 chirps and 512 range gate，the max detected range is 22m，range fft and doppler fft，summation oacross all channels，get a range-doppler matrix，the size of the matrix is 32×512，3d plot and zero doppler plot as follow，
the distance between iwr6843isk and the ceil is about 2.2m，range gate index is 51，
what the othe peaks detected stand for ？？？
we repeat the experiment in the open playground，iwr6843isk's antenna is aiming at the air, there is no anything but air in the sky, we get the results as follow，
the front several peaks in the zero doppler plot stand for ？？？there is nothing in the sky. some peak may be higher than the real goal's peak
How to delete these peak points that is not exist ？？？

How to delete these peak points that is not exist ？？？
run the srr demo program on the iwr6843, 2 Tx and 4 Rx, iwr6843isk's antenna is facing the ceiling in the room, many detected points are display on the GUI,
run the srr demo program on the iwr6843, 1 Tx and 4 Rx, iwr6843's antenna is facing the ceiling in the room, several points are detected points are display on the GUI,
3 points are detected at most.
What makes such a big difference bewteen the 1 Tx 4 Rx program demo and the 2 Tx 4 Rx program demo ？？？
How to eliminate these points that does not exist ？？？

many thanks
