The PSR is technically based on a noise radar. It is ideal to do pulse mode training, as it can handle disturbances and clutter which we have a lot in laboratories very well.
Technically we could also make it operate as a CW or in Doppler mode, but it did not bring such a good CW performance which we were able to accomplish with the FMCW base module.
Therefore we suggest for CW, FMCW, Doppler or FSk (Frequency Shift Keying) to use the FMCW based module. It is a great tool and very economic too.
