摘要本文以典型脉冲体制信号为研究对象,包括脉冲多普勒信号、伪码调相与脉冲多普勒复合信号以及伪码调相与脉位复合信号,研究的目的是为了适应无线电引信技术的高速发展。因为现代战场随着因新技术的高速发展已经越来越发展为无线电的战场,而引信环境也日趋恶化,敌我双方为了获得更低的截获概率和更好的抗干扰能力,引信采用的调制信号已经越来越复杂,主要的表现有:信号的特征参数较之前更多,参数也更加隐蔽。这给信号侦察带来了很大的难度。因此能够快速并准确地提取出引信信号的特征参数,已经成为了一个重要的研究方向。本文的工作包括以下几个方面:
(1)研究一些典型脉冲体制信号的工作原理;25859
(2)研究了PN码的m序列的游程长度排列规律,提出了基于游程长度排列规律的PN码特征参数提取,以及PAM伪随机码、PPM伪随机码的参数提取方法;
(3)研究了ZAM分布及其性质,提出了基于ZAM分布的伪码调相信号的特征参数提取方法;
(4)根据伪随机码以及伪码调相信号的参数提取方法,提出了提取伪码调相与脉冲多普勒复合信号以及伪码调相与脉位调制复合信号的参数提取方法;
(5)利用雷达上采用的方法来对脉冲多普勒的参数进行技术。

Title    Study on the extraction method of typical pulse
          pulse signal parameters                     
Abstract
In this paper ,the typical pulse signal system are studied, including pulse Doppler signal, pseudo random code phase modulation and pulse Doppler signal and pseudorandom code phase modulation and pulse position composite signal. The purpose of the study is to adapt to the rapid development of the technology of radio fuze. Because the modern battlefield as a result of the rapid development of new technology has been more and more development for the radio of the battlefield, and fuze environment is getting worse, both our own and that of the enemy in order to obtain lower intercept probability and better anti-interference ability, with the fuse modulated signal has become increasingly complex, main performance: the characteristic parameters of the signal more parameters more subtle. The great difficulty to the detection signal. It can quickly and accurately extract the characteristic parameters of fuze signal, has become an important research direction.The main work of this paper includes the following aspects:
(1)the working principle of some typical pulse signal;
(2) studied the run length of the PN code of m sequence arrangement rule, is proposed based on run length arrangement of the PN code feature parameter extraction, and PAM pseudo random code, PPM pseudo random code parameter extraction method;
(3)studied the ZAM distribution and its properties, put forward a method to extract characteristic parameters of phase coded signal based on ZAM distribution;
(4) according to the pseudo random code and pseudo random code phase modulation signal parameter extraction method was proposed for the extraction of pseudo random code phase modulation and pulse Doppler signal and composite pseudorandom code phase modulation and pulse position modulation signal parameter extraction method.
(5) using the method of radar to study the extraction of parameters of the pulse Doppler technology.
