Hi i need to realize a FMCW doppler estimation radar with one single Adalm-Pluto operating in full-duplex, programmed with Matlab. The estimation is always uncorrect but i don't know the reason because every time i try tu simulate without the Pluto SDR the estimation is correct. I tried also to separate the 2 antennas to remove the energy's dependence but the result are always wrong. How should i configure the device to resolve de problem? I am sure that the code about the digital elaboration is correct because when i try to simulate with an ideal ambient emulate with Matlab the estimation is correct
Your question sounds a little to specific to be handled here. There are many knobs on the ADALM Pluto that can be tuned to your specific application.
Since i want to realize a Radar application my goal is to receive the reflected signal. For this operation i use the capture and transmitrepeat of matlab but the signal that i captured i think is instead of the reflected signal, the trasmitting signal. Is it possible with one single adalm pluto realize a radar FMCW application in Matlab?
To estimate the velocity of the target and so the doppler variation
Yes this is possible to do. The emitted (not reflected copy) will always exist in your receive data. It must be canceled or identified so you can measure the Doppler or time delay of the reflected signal. Does you simulation code handle this signal? If not I would start by trying to model it.

what should i do to canceled it? Could you please release the code to eliminate the transmit signal from the receive data?
Radar algorithms are really out of the scope of our support here. You would need to look at the literature or see if existing implementation are available in something like MATLAB.

For the istantiation of the transmitter and receiver objects i use the following toolbox:
i need other toolbox to execute the transceiver operation correctly?
If not I would start by trying to model it.
If you were able to implement this functionality, can you please share how were you able to do this?
Thanks in advance if you share it.

Hi, I’m currently working on something related as well. Could you share how you approached it? How did you make it work?
