Phase-coded CW radar systems use instead of the widely used frequency chirp a phase-modulated transmission signal. This approach may have advantages for certain implementation and gives new opportunities due the additional degree of freedom especially in signal design.

To verify our novel approaches, we have built our own software defined radar platform. This device offers 4 IQ-transmit and 4 IQ-receive channels which are fully synchronized at a sampling rate of 500 MSPS. For example, with the 77 GHz 4x4 MIMO frontend, we carried out range-Doppler measurements in our anechoic chamber.
