Square wave architectures for radar-on-chip

Square waves enable radar implementation in modern digital technology giving power-efficent, compact and flexible radar solutions. Using a simple square wave generator and a sweep threshold quantizer we can realize a PN-sequence radar as well as a CW, SFCW, FMCW or a pulsed radar. The square wave receiver can utilize a digital XOR gate as a mixer and we present post layout simulations confirming our high level modelling.
