abstract = "As a sonar transmitted waveform, binary phase-shift keyed (BPSK) signal has a nearly ideal ambiguity function. The good Doppler and time resolution properties make BPSK signal advantageous for underwater targets detection. Under the Doppler perturbation situation, the property of good Doppler resolution will result in a sharp decline in detection performance. In recent years, waveform fusion has got extensive attentions. A novel waveform combining BPSK signal and a Doppler insensitive signal can improve the performance of target detection in case of perturbation. This article focuses on the study of ambiguity function, time and Doppler resolution of LFM-BPSK signal, furthermore we studied the detection performance of linear frequency-modulated (LFM), BPSK and LFM-BPSK signals in the presence of perturbation. Simulation results show that the LFM-BPSK signal has a stronger anti-perturbation proformance than BPSK signal.",
