AWR1243BOOST: the data capture by TSW1400 EVM is not continuous and may be wrong

Part Number: AWR1243BOOST
Other Parts Discussed in Thread: AWR1243

hi, recently, I use the TSW1400EVM + AWR1243 boost + Dev pack to capture the raw data .

I send the radar parmeters just like below:

profileCfg 0 77 360 6 40 0 0 100 1 64 2000 0 0 48

frameCfg 0 128 128 0 55 1 0

and when TSW1400EVM capture raw data, I move my hand cyclic. but after doing 2-D FFT in the raw data I get, there is no range and doppler change in it

I think it is wrong . Can anyone tell me why?

Hi Pengcheng,

I've asked a TSW1400EVM expert to look into this query and someone should have an answer for you Monday.

Cheers,
Akash

Hi,

Can you please place a corner reflector and capture the data?

You should be able to detect it

thank you

hi, I move a metal cup in front of the radar. ok, in fact, I can get the raw data, but the cup is moving, in PostProc, the 2-D fft should have range and doppler change in the map. But , there is no change . So that is why I say the capture data is wrong
