摘　　要：针对等脉宽随机脉位脉冲信号脉位随机性不强的问题,提出了随机脉位线性调频脉冲信号(RPP-LFM)的概念,并对其产生方法、脉冲平均密度、脉冲平均脉宽、脉冲平均重复周期、随机脉冲序列的自相关性、模糊函数以及各个脉冲的载频特性进行了深入的研究,分析结果说明该信号形式既具有雷达信号的特点,可以作为雷达信号使用,又具有宽带噪声的遮盖特性,可以作为电子攻击信号使用,是一种重要的信号形式,具有作为未来一体化系统使用的共用信号的潜力。Aiming at the poor randomicity of the random puls position signal with same pulse width, the concept of random pulse position and linear frequency modulation（RPP - LFM） pulse is presented. RPP - LFM＇s coming into being, average pulse density, average pulse width, average pulse repeating interval, self - correlation of random pulse position, ambiguity function and the carrier frequency of every pulse are studied in detail. The analytical results demonstrate that RPP - LFM pulse not only has the characteristics of radar signal, which can act as radar signal, but also has the jam - up characteristic of wideband noise, which can act as EA signal. So RPP - LFM pulse is an important pulse style , as a community signal it would be used in future integrative system.
