摘　　要：当目标在红外成像焦平面上呈现为点目标时,投放红外干扰弹能够有效的实现对红外导弹的干扰。建立了点目标图像辐照度高斯模型和点目标图像红外辐射功率计算模型。在研究红外干扰弹对目标特征长度和红外辐射能量等效中心辐射强度的干扰基础上,分析了红外干扰弹对点目标图像辐射特性的干扰。最后,给出了干扰弹与目标距离、干扰弹辐射强度、面积与点目标图像辐射强度中心功率的关系,得到了红外干扰弹对点目标图像辐射特性干扰图像仿真结果。When the target looks like the point target in the imaging infrared focal plane, the countermeasure can be executed to the infrared missile by using the infrared decoy. The Gauss model of point target image irradiance and the calculation model of the infrared radiation power are established. Based on the researching of the infrared decoy countermeasure to the target characteristic length and energy equivalent centre, the countermeasure to the point target image radiation characteristics are analyzed. At the end, the relationship of the distance between decoy and target, radiation intensity, radiation area and the strongest radiation power of the point target image are given, the simulation results are performed.
