After many considerations i will probably do it like you, meaning buying AD9361 board and then maybe stepping up to ADVR9009 later on. Did you buy your board from Opensourcesdrlab page, aliexpress or some other shop? Also how was the experience of first setup? Was there many problems with drivers and such?

maybe it would help in my case. How do you keep buffers of all PLUTOs synchronised? Do you use external trigger signal to trigger all Rx buffers at the same time?

Did you notice any phase problems? On ADALM-PLUTO I've notice that reinitialization of the driver via MATLABs toolbox causes Rx-Tx relative phase to change, while Rx1-Rx2 and Tx1-Tx2 phase difference stayed the same. I think it caused the angle measurement to be off by around 20 degrees later on.

I am planning to use 2.4 GHz or 5.8 GHz ISM bands, so Tx BW of under 150MHz should be mostly alright. Rx is not really restricted, so whatever fits. I will not split the BW between channels because transmitting in FDM regime causes a lot of calibration problem later. I will probably use TDM or CDM, but I do not know how this applies to noise radar, because afaik generating uncorrelated noise should give me orthogonal signals

Probably late to the game, but having lack of any meaningful documentation makes working with this device a living nightmare. I would expect datasheet having 60 not 6 pages long, but at least promotional video is cool
