摘　　要：针对电子干扰和隐身目标的威胁日趋恶化的趋势 ,本文研究了电子对抗环境下T/R R型双基地雷达如何运用数据融合实现对隐身目标的三维跟踪问题 .按照无 -弱—较强—强的干扰强度变化 ,提出了双基地雷达采取不同观测子集对隐身目标的跟踪技术 ,对不同干扰方式下双基地雷达对隐身目标的测量误差以及双基地雷达截面积的计算进行了讨论 ,建立了电子战环境下双基地雷达对隐身目标的测量模型 ,给出了几种典型情况下的计算机仿真结果 。Against increasingly worsened situation caused by ECM and stealthy targets, this paper investigates the scheme of 3-D tracking for stealthy targets by T/R-R bistatic radar using data fusion in EW environment. According to the jamming intensity varying from no-jamming, weak-jamming, less-strong-jamming, to strong-jamming, this paper presents a tracking technique which makes use of various observation subset of bistatic radar against stealthy targets, discusses the measuring error of bistatic radar against stealthy targets and the computation of bistatic radar RCS under various jamming styles, and establishes a measuring model of bistatic radar against stealthy targets in EW environment. The computer simulation results in some typical cases are given to prove the validity of bistatic radar in the struggle of anti-stealthy targets.
