摘要
Abstract
Passive TDOA location system can detect and locate radiation sources in the air/ground/sea.This system has some advan-tages,such as electronic counter-countermeasure,anti-reconnaissance,counter anti-radiation missile and detection of stealth targets.Because the height baselines are relatively short when multiple stations are deployed on the ground,the positioning height error of the TDOA is large,the accuracy of the target indication information is reduced and the target attack effect is affected.Aiming at the prob-lem of poor position accuracy of target height in TDOA location system based on ground distribution stations,the joint location method based on the angle measurement information of the passive seeker on anti-radiation missile and TDOA location system is adopted.This paper presents a joint positioning method.Target height error was deduced detail in theory,the influence of passive seeker's position and angle measurement precision of target on height error is simulated.Finally,several constructive suggestions are made for practical engineering applications based on the result,this method has high engineering reference significance.关键词
