不同干扰决策准则下的双基地雷达探测能力研究

针对双基地雷达具有的四抗优势,本文基于决策准则研究了不同干扰方式下双基地雷达的探测能力.从能量角度出发推导了双基地雷达方程和干扰方程,建立了双基地雷达探测区的计算模型,探论了悲观准则和乐观准则下双基地雷达探测能力的变化规律,研究了自卫干扰和远距离支援干扰对双基地雷达干扰暴露区的影响,给出了几种典型情况下的计算机仿真结果,并通过分析得出了一些有益的结论,为双基地雷达的布站和抗干扰能力分析提供了重要的理论价值,也验证了双基地雷达比单基地雷达具有更强的抗干扰能力.

Detecting Capability of Bistatic Radar under Different Jamming Decision Criterion

Against Four Countermeasures advantage of bistatic radar,this paper investigates bistatic radar's detecting capability on the condition of different jamming style based decision criterion.From the view of energy this paper educes bistatic radar equation and jamming equation,establishes calculation model of bistatic radar detection range,discusses the variety rule of bistatic radar's detection capability under the pessimism and optimism decision criterion,and studies the effect of Stand-off Jamming and Stand-forward Jamming towards bistatic radar jamming exposed range.The computer simulation results in some typical cases are given.As a result,some useful conclusions are drawn by analysis,which provide important theoretic value for allocating bistatic radar and analyzing anti-jamming capability,and prove that bistatic radar has the stronger anti-jamming capability than single radar station.
