诱饵参数对面源红外诱饵干扰效能的影响

Influence of parameters of decoy on jamming effectiveness of surface source infrared decoy

面源红外诱饵作为一种主动干扰型的红外对抗装备,与传统的红外诱饵弹相比,在运动特性和干扰效能等方面有显著的优越性。综合考虑到试验的成本和干扰效能评估的效率,文中提出了一种基于空战对抗仿真算例的效能评估思路:首先,建立了导弹运动模型、介绍了跟踪优化算法和抗干扰识别算法;其次,重点分析了飞机蒙皮红外辐射特性的求解过程;然后,分析了诱饵箔片的运动扩散模型以及燃烧优化算法;最后,改变面源诱饵的参数,如发射角度、发射高度以及发射速度,进行干扰成功率的仿真计算。将仿真结果与实测数据进行比对,验证了效能评估思路的可行性,基本满足干扰效能评估的要求。

Surface source infrared decoy regarded as an active interference type infrared countermeasure equipment, compared with traditional infrared decoy, has obvious superiority in motion characteristics, jamming effectiveness and so on. Considering the economy of cost and evaluate efficiency, a kind thought which could simulate the testing work based on air confrontation examples was proposed. Firstly, the missile motion model,tracking optimization algorithm and anti-jamming recognition algorithm were established. Secondly, the infrared radiation characteristics of the aircraft skin was focused. Then the motion model of decoy foil was built and the combustion algorithm was optimized. Finally, through changing factors, such as the launch angle, height and speed of decoy, jamming effectiveness was tested. The simulated result is close to real data, verifying the effectiveness evaluation thought is feasible and basically meeting the demand of evaluating.
