摘　　要：针对在一次雷达方位牵引条件下使用的机载敌我识别询问机,载机转弯段存在波束指向偏差大的问题,深入分析了误差来源并对误差影响程度进行了仿真分析,指出载机转弯时,若按照雷达的指示方位设置敌我识别询问机波束指向,波束不能够对准目标。提出了一种机载询问机的波束指向偏差修正算法,修正了敌我识别询问机波束指向并进行了仿真验证。仿真结果表明:所提出的修正算法能够使敌我识别询问机在载机转弯段维持高指向精度,促进了机载敌我识别/二次雷达系统的发展。For the airborne identification friend or foe(IFF)interrogator used under radar azimuth traction condition,there is an issue of large beam pointing deviation during the aircraft turn section.In this paper,the deviation source is deeply analyzed and the impact degree of the error is simulated,it points out that the beam of the IFF interrogator cannot able to be aligned with the target if the beam pointing is set according to the indicated direction of the radar.In this paper,a beam pointing deviation correction algorithm for airborne interrogators is proposed,which corrects the IFF interrogator’s beam pointing,and simulation verification is carried out.The simulation results show that the correction algorithm proposed in this paper provides the capability for maintaining high direction accuracy of the IFF interrogator during the aircraft turn section,and promotes the development of the airborne IFF/SSR system.
