摘要:

针对雷达信号射频隐身性能评估中对敌方截获设备的依赖性和评估方法通用性的问题,提出一种基于自身辐射信号特征的雷达信号波形射频隐身性能评估方法。该方法从射频辐射源自身辐射信号的结构出发,通过分析辐射源所辐射信号的周期、占空比,利用希尔伯特变换求出单一周期内脉内信号的瞬时频率、瞬时波形、瞬时相位,归一化脉内信号瞬时参数,从而给出波形域射频隐身指标的定量计算方法。对雷达信号的线性调频波形和相位编码波形进行了仿真对比,仿真结果证明此方法可准确反映出雷达信号波形域射频隐身性能。

Abstract:

In order to solve the dependence on enemy intercept equipment and the limitation of the evaluation method in the evaluation of radar signal radio frequency (RF) stealth performance, a radar signal waveform RF stealth performance evaluation method is proposed based on the characteristic of selfradiation signals. Based on the structure of RF radiation signals, this method analyzes the period and duty cycle of the signal radiated by the radiation source, uses Hilbert transform to derive the instantaneous frequency, phase and waveform in a signal cycle, and normalizes the signal parameters. Then a quantitative calculation method for RF stealth in waveform domain is proposed. Compared with the simulation of waveform and phase-code of radar signal, this method can accurately reflect the performance of radar signal RF stealth.
