T-R型双基地跟踪雷达有关问题及仿真分析

雷达在电子对抗中起着极其重要的作用。本文针对T-R型双基地跟踪雷达,分析了系统的特殊性及要解决的关键技术问题,介绍了发射站和接收站之间的时间同步、频率同步和空间同步技术,分析了传统的单基距解算方法的不足,讨论了基于调整发射站触发脉冲和接收站测距同步脉冲两种距离解算方法,对双基地雷达测量值的校准方法进行了描述,最后对双基地雷达的定位准确度及采用联网多基地雷达系统提高距离的定位准确度进行了研究。仿真结果表明,联网双（多）基地雷达的数据融合,可明显改善基线附近的单基距准确度。

Relevant problems and simulation analysis on bistatic tracking radar of T-R

Radar plays a great role in electronic antagonizing.The special characteristics of system and key technique problems needed to be solved on bistatic tracking radar of Transmitter-Receiver（T-R） type were analyzed.The time synchronization technique,the frequency synchronization technique and space synchronization technique between transmitter station and receiver station were introduced.The deficiency of traditional single range solving method was analyzed.Then two range solving methods based on adjusting the transmitted spring pulse and received range synchronization pulse were discussed.The time calibration methods on the measure value of bistatic radar were described.Finally the position precision of bistatic radar and the improvement on position precision of range by adopting networking multi-static radar system were studied.The simulation results show that the networked bi-（multi）static radar systems can apparently improve the ranging accuracy near the baseline by data fusion.
