摘　　要：无源时差定位系统能够对空中/地面/海面辐射源进行侦收定位,具有抗干扰、反侦察、防反辐射导弹和反隐身等潜在优势,由于多站在地面布站时,高度基线比较短,导致时差定位高度误差较大,降低目标指示信息的准确性,影响目标的打击效果。针对地面布站的时差定位系统目标高度定位精度较差的问题,采用了基于反辐射导弹上的被动导引头的测角信息和无源时差联合定位方法,在理论上详细推导了目标高度定位误差,仿真分析了导引头位置、角度测量精度对目标高度精度的影响。最后,基于仿真实验的结果,给出一些应用性的实验结论和建议,该方法具有较高的工程参考意义。Passive TDOA location system can detect and locate radiation sources in the air/ground/sea.This system has some advantages,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 problem 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.
