用于红外成像导弹抗干扰测试的仿真模型

Simulation model for countermeasure test of IR imaging missile

红外干扰技术的发展制约了红外型导弹的作战效能,抗干扰能力的测试评估是导弹研制过程中所必须考虑的。单纯地通过实验进行抗干扰性能测试评估不仅耗费时间、增加成本,且所能考核的条件也非常有限。通过理论分析和实测数据建立了典型的空中目标和诱饵干扰的红外辐射模型及相对运动模型,并考虑大气因素的影响,构建出导弹动态条件下抗干扰性能的测试评估环境,分析了诱饵干扰的投放间隔、距离、方向、数目、目标机动等多种因素对抗干扰性能的影响,从而完善了对导弹抗干扰性能指标的评估。

The development of infrared jamming technology restricts the fighting efficiency of infrared missiles. The test and evaluation of countermeasure capability are the important factors that must be considered in the development process of missiles. Only using experiment to test and evaluate the countermeasure performance wastes time and increases cost. And the evaluations conditions are very limited. Infrared radiation model and relative motion model of airborne target and decoy jamming were built with the theoretical analyses and experiment data. Considering the atmosphere effect,the test and evaluation conditions of countermeasure was proposed when the missile was under dynamic conditions. There were many factors which effected the countermeasure were analyzed,such as aerial-launching interval,distance,orientation,numbers and target maneuver etc. The test results show that the evaluation standards of missile countermeasure characteristics were perfected.
