Hello,
I am studying the influence of radar profile setting on target detection using AWR1642 and a corner reflector.
When I change the FMCW frequency slope and keep everything else unchanged ( by which bandwidth is modified from several hundred MHz to several GHz ),
the received signal power from corner reflect changes greatly (over 20 dB)...
This large change in the received signal power is not expected nor explainable.
Would you please give some advice or comment on this issue?
Thank you in advance!
Below is some hardware configuration and experiment setting.
Target is placed ~10 m in front of the radar.
AWR1642 ES1.0, data collected using DCA1000 + mmWaveStudio. (and built-in postproc for data analysis)
Frequency slope is changed from 1 MHz/us to 10 MHz/us
HPF setting is HPF1 175K, HPF2 350K
