摘　　要：随着隐身与反隐身技术的不断发展以及机动突防与防空策略在军事上的大量运用,研究目标的电磁散射特性对于攻防双方都具有重要的意义。文中以F-22作为典型隐身目标,将目标、雷达相对位置与全空域雷达散射截面积数据库相结合,从双基地雷达方程出发,分别从不同雷达基线长度和不同雷达站相对位置两个方面进行分析,仿真结果表明,双基地雷达的探测范围会随着雷达基线长度的增加呈现出先增加后减小的趋势,且雷达的相对位置严重影响了其探测范围及探测距离。该结果为预警雷达抗突防、反隐身等方面提供了理论分析和实验依据。With the continuous development of stealth&anti stealth technology and maneuverable penetrating air defense strategy mass military application,target electromagnetic scattering characteristics research has great significance for both the offense and defense.Based on F-22 model typical stealth target,This paper combines target,radar related position with whole airspace RCS database,analyses the target from different situation,which links radar baseline lengths and radar station related positions with bistatic radar equation.The result of simulation indicates that when the radar baseline length increasing,bistatic radar detection range presents a trend of increasing first and then decreasing,and radar related position affects its detection range and distance severely.This result provides theoretical analysis and experimental evidence for early-warning radar maneuverable penetrating and anti-stealth ability.
