摘要:
研究了EBPSK(extended binary phase shift keying)调制脉冲雷达信号的探测性能.首先分析了该雷达系统信号在几种情况下基于CFAR(constant false alarm rate)的目标检测概率,表明在未知目标距离情况下,EBPSK调制雷达信号的探测性能优于传统LFM雷达信号的探测性能,在短波信道中,EBPSK脉冲雷达信号不存在多普勒频扩.该信号的模糊函数是对称的,所以不存在距离-多普勒耦合效应.其次,EBPSK调制雷达系统的调制器灵活多变,可根据要求设置不同的调制参数以改变信号的测距精度与目标探测性能.最后,通过仿真实验验证了理论分析的合理性,在较大脉冲回波时延估计误差的前提下,EBPSK信号的脉冲压缩性能高于LFM的脉冲压缩性能,且获得相同的探测性能,当时延大于0.05 μs时,EBSPK脉冲雷达信号所需SNR比LFM脉冲雷达信号要少;当时延为0.5 μs时,EBSPK脉冲雷达信号所需SNR比LFM脉冲雷达信号少25 dB.
Abstract:
The detection performance of the EBPSK(extended binary phase shift keying)modulated pulse radar signal is studied. First, the target detection performances based on CFAR(constant false alarm rate)of the proposed signal are analyzed under several conditions. The detection performance of the proposed signal is better than that of the LFM radar signal under the condition with unknowntarget distance. EBPSK pulse radar signal can combat the effect of Doppler spread on system performance in HF(high frequency)channel. The ambiguity function of the proposed signal is symmetric, so Range-Doppler coupling effect does not exist. Secondly, the signal modulator in EBPSK modulation radar system is flexible. According to different requirements of ranging, the ranging accuracy and target detection performance of the system are varied by setting different modulation parameters. Finally, the correctness and rationalization of the theoretical considerations is verified by the results of experiment. The pulse compression performance of the EBPSK radar signal is better than that of the LFM radar signal under the condition of larger delay estimation error of echo pulse. To obtain the same detection performance, the required SNR of the proposed signal is less than that of the LFM signal when the echo delay is greater than 0.05 μs. The required SNR of the proposed signal can be decreased by approximately 25 dB compared with that of the LFM radar signal when the echo delay is 0.5 μs.
