Abstract

In Phase-Modulated Continuous Wave (PMCW) radar the phase symbols can be approximated by constellation points from a quadrature transmitter. However, this leads to mapping errors w.r.t. the ideal symbols. This paper evaluates the effects of the mapping errors in P4 polyphase codes on the performance of PMCW radars based on quadrature transmitters. Two methods are analysed to reduce these errors. Firstly, rotating the phase symbols in the constellation before mapping to the constellation diagram is analysed. Secondly, the effect of applying dither is analysed. System-level simulation results validate both methods and show improvements of the relative sidelobe level exceeding 20 dB.
