一种新的雷达动目标检测方法

A new detected method of the radar moving targets

基于线性调频(LFM)脉冲压缩雷达原理及雷达动目标显示(MTI)的数学模型,通过与传统二脉冲对消和三脉冲对消的方法相对比,采用四脉冲对消和参差脉冲重复频率处理盲速的方法进行动目标检测。仿真实验证明,在动目标检测中使用线性调频脉冲压缩的四脉冲对消和参差脉冲重复频率方法,能够更好地提取杂波中的运动目标。

Using four-impulse and varying pulse repetition frequeney of consumption deal with blind speed detect moving target. Contrast with the traditional method of using two or three-impulse frequency of consumption in this paper based on the principle of linearity frequency modulation （LFM） Pulse-compression radar and the mathematical model of radar moving target indicator （MTI） of the paper is established. Theory and simulation results show that the ability of detecting moving targets under the noisy situation can be improved perfectly by the methods of using Pulse-compression four-impulse and varying pulse repetition frequency of consumption.
