摘　　要：为了提高打击地面目标无线电引信定向起爆控制能力,提出一种基于合成孔径雷达(SAR)的对地无线电引信目标定向算法。通过构建弹目交会场景,采用SAR原理合成得到窄波束,对两波束的回波信号进行和差计算得到目标与弹轴的夹角。仿真结果表明,该算法对弹目交会角在39°~64°的方向,目标定向识别误差不大于1.2°,表明了SAR技术能够大幅提高无线电引信对目标的定向精度和算法的泛用性,能够为无线电引信目标定向起爆技术提供技术支持。In view of the demand for directional detonation control capability of radio fuze for strike ground targets,a SAR-based ground fuze target orientation algorithm was proposed.By constructing the intersection scene of the projectile to design the pattern of two identical and intersecting fuse antennas,SAR synthesis was used to obtain narrow beams,and the echo signals of the two beams were calculated with the difference.The simulation results showed that the error of the algorithm for the direction recognition of the intersection angle of 49°~64°was not more than 1.2°.It was indicated that the SAR technology could greatly improve the angle measurement accuracy and the versatility of the algorithm,and provide support for the directional detonation technology of radio fuze target.
