ABSTRACT
Reed-Muller codes were used in radar signal processing to determine the sequence transmitting order of Golay complementary waveforms for radar illumination to get an improved detection performance on atargetofnonzero Doppler. In this paper, we consider the detection case where multiple targets with nonzero Doppler are present. We propose a signal processing procedure which achieves an enhanced illumination performance by applying the combination of the Reed-Muller codes and the Binominal Designto the Golay omplementary waveform transmission sequences. The procedure consists of two processes. A Reed-Muller sequence is selected according to a weighted average Doppler algorithm. In the meantime, the Binominal Design algorithmis used to the receiving weights of Golay complementary waveforms as well. After match filtering, the minimum output values of the two processes are point-wisely operated as thefinal output. Simulated results show that the proposed signal processing procedure has a better detection performance in the sense of lower sidelobes and higher Doppler resolution for nonzero Doppler targets against the existing methods.
