Inter-period compensation algorithm implementation in full-polarimetric FMCW radar with continuous waveforms

Abstract

This paper describes a new type of sounding signals for polarimetric FMCW radar and the corresponding signal processing technique. The inter-period compensation (IPC) algorithm is proposed for isolation increase in radar channels. The novelty concerns the use of orthogonal polarizations of two bi-cyclic LFM-signals having an additional phase shift every second sweep. Summation units proposed for use in the receiver channels allows for reducing the effects of interfering signals due to the specified phase of received signals over two consecutive sweep times.
