Research Of Passive Location Technology In Different Platform

With the development of electronic countermeasure and radar technology,passive location technology is more and more important in modern war because of its characters,such as capability of cover-up,position far and strong anti-jamming-power.This text gives a brief introduction to passive location of its development backgrounds and present states,firstly research the passive location technology of EW system in three different platforms,give the basic principle,appropriate arithmetic and results of simulation,then make the analyse and simulation of location capability in each platform,with the analysis of data and result form the application.This text also give the basic arithmetic and simulation for passive location based on the characteristic of each platform,analyse the location accuracy and the factors which affect it.Accordingly some valuable emulational results are obtained,which provide definite technical reference for the research and application in this field.
