| 摘 要： | 针对线性调频信号形式简单,易被敌方截获和干扰的特点,提出了一类脉内线性调频和子脉冲相位调制相结合的具有多种变化形式的混合调制脉冲压缩信号。MATLAB仿真分析表明,与单纯线性调频信号相比,该混合调制信号产生和处理简单,既保持了线性调频信号的优点,又提高了抗截获和抗干扰能力。

| Abstract: | The traditional LFM (Linear Frequency Modulation) signal is easy to be intercepted and jammed because of the simple waveform. This paper proposes one kind of FM-PM co-modulated pulse compression signal obtained by combining in-pulse linear frequency modulation and sub-pulse phase modulation. Through the analysis and MATLAB simulation of anti-jamming, it has been proved that this co-modulated signal has the advantages of higher ability for anti-interception and anti-jamming, and the co-modulated signal can be easy generated and processed. |

| Keywords: | LFM phase modulation co-modulation anti-jamming simulation |
