摘　　要：双机IRST系统协同搜索是一种重要的无源探测手段。分析了双机IRST协同搜索关键问题,建立了自主引导搜索的数学模型,通过长机IRST系统探测到目标的角度信息,并利用IRST系统的探测距离范围限制计算目标在僚机机体系中的角度范围,据此引导僚机IRST系统对目标存在区域进行搜索。对于僚机搜索范围提出顺序搜索和中心搜索两种搜索策略,仿真结果表明了引导搜索的有效性,中心搜索比顺序搜索效率更高,所需时间更短。其中,根据中心搜索策略提出的两种一次搜索方案的仿真结果验证了成功引导搜索的性质,对研究双机IRST自主引导搜索系统配置具有一定的参考价值。The cooperative search with double-plane IRST system is an important passive detection method.Analysis is made to the key problems in double-plane IRST system cooperative search,and the mathematic model for autonomous guiding search is established. Through the target angle information detected by IRST system of the lead aircraft,the angle range of target in the wing aircraft＇s body axis system is obtained by using detection distance coverage limits of the IRST system. Then,the IRST system of the wing aircraft is guided to search the target area according to the angle range. Two search methods,sequential searching and central searching,are put forward for IRST system of the wing aircraft. The simulation result shows that the autonomous guiding search is effective,and the central searching is more efficient and takes less time. The successful guiding probability is verified by the simulation results of two schemes according to the central searching strategy. The conclusions are helpful for designing double-plane IRST guiding systems.
