摘要:
为了解决二次监视雷达(SSR)接收到目标应答信号时受到异步干扰的问题,在SSR对目标的应答信号的脉冲宽度内,引入扩展二元相移键控(EBPSK)对载波进行相位编码调制.理论分析了SSR系统中速度与频偏的关系,通过研究EBPSK相位调制脉冲的波形特点,提出了将EBPSK相位编码脉冲信号作为SSR系统应答信号的方案,从而有效利用异步干扰提升双基站SSR系统的目标测速精度.理论分析与仿真实验结果表明,在目标测速精度方面,EBPSK相位编码的双基站SSR系统明显优于EBPSK相位编码以及纯正弦调制脉冲的单基站SSR系统.因此,验证了EBPSK相位编码脉冲信号在双基站雷达系统中的有效性和可行性.
Abstract:
To solve the problem that the target response signal of secondary surveillance radar(SSR)is interfered by the asynchronous interference, the extended binary phase shift keying(EBPSK)is introduced for carrier phase coded modulation within the radar pulse width. The relationship between the target speed and the deviation of frequency in the SSR system is analyzed theoretically. By studying the waveform characteristics of the EBPSK-based phase-coded pulse signal, a scheme taking EBPSK-based phase-coded pulse signal as the response signal in the SSR system is proposed, where the asynchronous interference of the SSR system is used effectively to improve the precision of speed measurement. The theoretical and simulation results show that the speed measurement precision of bistatic SSR signals with EBPSK modulation is better than that of single SSR signal with sine and EBPSK modulation. Therefore, the efficiency and feasibility of the EBPSK-based phase-coded pulse signal is verified in the bistatic SSR system.
