摘　　要：为实现红外图像末制导炸弹全弹道捕获区域的快速计算,通过分析导引头的瞬时捕获域条件,以导引头中轴线为中心,利用坐标变换建立了红外图像末制导炸弹的瞬时捕获域模型;给出了不同视场角的瞬时捕获域形状,在此基础上提出了红外图像末制导炸弹的全弹道捕获区域快速计算方法。分析了全弹道捕获域的过程,假设炸弹飞行过程中弹道倾角不变,分别给出了采用平台型导引头和捷联型导引头的红外图像末制导炸弹全弹道捕获区域的快速计算方法。分别对采用追踪制导律和大落角制导律的某型红外图像制导炸弹的全弹道捕获区域进行了仿真分析,结果表明,提出的快速计算全弹道捕获区域与仿真结果误差较小,可用于红外图像末制导炸弹全弹道捕获区域的快速计算。To rapidly calculate the total capture area of infrared-image terminal guided bomb （TGB）, the condition of the instant capture area was analyzed, and the middle axis of the seeker was taken as center, and the instant capture area model was established by using coordinate transformation. The shape of instant capture area in different field of view was given. On this basis, the rapid calculation method of total capture area of infrared-image TGB was proposed. Under the constant, the total capture area of the guided bomb with the assumption of the flight path angle keeping gimbaled seeker and the strap-down seeker were put forward respectively. The total capture area for the infrared image TGB guided by tracking method and the large angle of fall guidance law was simulated, respectively. The results show that the total capture area by the rapid calculation is in agreement with the simulation result, and the rapid calculation can be used for the fast calculation of the total capture area of infrared-image TGB.
