摘要:

机载动目标显示(AMTI)技术广泛应用于机载雷达系统,用于抑制和衰减地物等静止物体的背景回波信号。文中根据AMTI的基本原理,提出利用AMTI抑制箔条慢动杂波的方法,并建立基于AMTI的机载雷达信号处理系统模型,利用该系统对目标飞机和箔条云回波信号进行信号处理仿真,对比分析仿真结果,验证了AMTI对箔条云杂波具有明显的抑制作用,为空战中利用AMTI技术抑制箔条杂波提供了理论依据。

Abstract:

Airborne Moving Target Indication (AMTI) is widely used in airborne radar system,to inhibit background echo signal of stationary object such as surface features.According to the basic principle of AMTI,this paper puts forward that chaff slow-moving clutter can be inhibited by AMTI,and builds a model of airborne radar signal processing system based on AMTI,using the system model to make simulation of signal processing for echo signal of target aircraft and chaff clouds.The comparative simulation results verify that AMTI can inhibit chaff cloud clutter significantly,and so provides theoretical basis of using AMTI to inhibit chaff clutter in the air battle.

Key words: AMTI;airborne radar;chaff clutte
