Dear experts
Here is my question .
In order to enhance the velocity resolution, I increased the number of chirps by two-fold and reduced the sampling rate by half.
Howerver,the power of TX decreases 1or 2dB at 0 angle,and there is a 5dB decrease in antenna transmission power at larger angles.
What is the underlying cause?
here are my chirp configration parameters
origin:
chirpnum = 32
rangebin = 512
change:
chirpnum =64
rangebin = 256
in the two methods,alternating transmission of two different waveforms within a frame
be like
chrip1: phase of TX1 is 0,phase of TX2 is 0
chirp2:phase of TX1 is 0,phase of TX2 is 180
Thank you!
