“…At present, there are several methods used to estimate PRBCPM-SFM signal parameters, such as spectral correlation [1][2][3][4][5], periodic ambiguity function [6,7], wavelets [8][9][10] and time-frequency distribution [11][12][13]. Extraction of mono-component PRBCPM-SFM signal parameters by using these methods yields satisfying results.…”

“…18; the CRLB (which is derived in Appendix B) curves are also shown in this figure. In addition, we compare the estimation performance with the spectral correlation method [1][2][3][4][5], the periodic ambiguity function method [6,7] and the wavelets method [8][9][10]. The NRMSE curves of the three methods are also drawn in Fig.…”

In the radar sensor network (RSN), the interferences among different radar sensors can be effectively reduced when waveforms are properly designed. In this paper, we perform some theoretical studies on coexistence of phase coded waveforms in the RSN. We propose a new ternary codes-optimized punctured Zero Correlation Zone sequence-Pair Set (ZCZPS) and analyze their properties. Applying the new ternary codes and equal gain combination technique to the RSN, we study the detection performance versus different number of radar sensors under the different conditions. The simulation results show that the RSN using our optimized punctured ZCZPS performs better than the RSN using the same number of common codes such as the Gold codes, and much better than the single radar system no matter whether the Doppler shift is considered or not.

“…As in a coherent-pulse-train radar, Doppler sidelobes in a CW radar can be suppressed by a weight function in the receiver. The discussion in [1] is extended here to include the effect of a weight function on the delay-Doppler response of CW radar signals. In particular we are concerned with the effect of nonuniform weight function on the property of perfect periodic autocorrelation.…”

CW radar signals and processors are discussed. The use of the periodic ambiguity function (PAF) to analyze the delay-Doppler performance of CW signals and their corresponding correlation receivers, is extended to include weight function effects. This work provides tools which can predict the delay-Doppler response of almost any phase-coded CW radar. Examples demonstrate that a combination of CW signals having perfect periodic autocorrelation, a matched reference signal with a large number of modulation periods and a smooth weight function, can create a delay-Doppler response with extremely low sidelobes, strongly resembling the response of a coherent pulse train.
