Cost efficient frequency hopping radar waveform for range and Doppler estimation

Abstract

A simple and cost efficient frequency hopping radar waveform which has been developed to be robust against mutual interference is presented. The waveform is based on frequency hopping on the one hand and Linear Frequency Modulation Shift Keying (LFMSK) on the other hand. The signal model as well as the radar signal processing are described in detail, focusing on the efficient estimation of range and Doppler of multiple targets in parallel. Finally, the probability of interference is estimated and techniques for interference mitigation are presented showing a good suppression of mutual interference of the same type of radar.
