First , we set up the models of linear frequency coded radar and two phase coded radar differently , and discuss the models in some degree 首先,本文分别构建了线性调频和二相编码雷达接收机的模型,并对其做了大量的数学分析。
The jamming of two models of pulse compressed radar , linear frequency coded radar and bi - phase coded radar , are studied in this dissertation 本论文讨论了脉冲压缩雷达中两种典型的雷达制式:线性调频雷达和二相编码雷达的干扰。
In the information environment of radar there are some signals such as regular and binary phase modulated pulse signal and linear frequency modulated signal are used widely 在雷达信号环境中,最常见的信号包括常规脉冲调制信号、脉内二相编码信号以及线性调频信号。对这些信号的载频测量在电子战中具有重要意义。
Pulse internal phase coding and pulse external quasi random frequency agile signal is a kind of complex signal which can avoid interference frequency band , increase system bandwidth , consequently increase the range resolution 本文所研究的脉内二相编码脉间准随机跳频信号是复合信号的一种,可以避开干扰频段,提高系统带宽,从而提高了距离分辨力。
We modulate the amplitude of the continuous single tune jamming by noise and produce the continuous noise - modulated jamming . this kind of jamming is effective to pc radar including linear frequency - modulated radar and bi - phase coded radar 在对单频正弦波进行噪声调幅后形成的噪声调幅干扰对线性调频雷达和二相编码雷达都是有效干扰,其干扰特性和射频噪声干扰类似。
