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
