激光调制型红外干扰条件下地面目标的识别方法

通过介绍激光调制型红外诱饵对地面目标干扰的工作原理和工作过程，分析基于灰度时间序列特性及序列图像运动特性的辨识方法在地面军械、装甲目标特征提取与真假识别中的应用。对于远距离变化平缓的点目标，其分辨灰度变化特性的方法包括傅立叶变换及小波变换：而对于运动剧烈变化的面目标则应用序列图像运动特性的目标识别，该方法可充分结合单帧图像中的目标历史状态信息，结合模糊集理论和信息融合技术，使运动目标在干扰条件下的识别具有较好的鲁棒性和适应性。实验证明，该方法能有效区分目标和诱饵，为红外干扰条件下地面目标的识别提供了理论模型和技术途径。

Methods of Ground Target Recognition Under Laser Modulation Mould Infrared Countermeasure Conditions

Introduce principles and courses of disturbance based on laser modulation mould infrared bait to the ground targets,and analyze applications of characteristics based on grey degree time sequence and discriminance of sequence image athletic characteristics to ground ordnance,armored target characteristics pick-up,and true/false target divisions. As for mild-changing distant point targets,methods of differentiating changes of grey degree characteristics include FFT and wavelet transform;but for acute-changing area targets,it uses the specific properties of alignment picture motion for target identification. It can fully combine the history state information in one frame picture,and using the theory of inkling and technologies of information amalgamation,while can make target recognition possess adaptability better. Experiment proves,the methods can distinguish effectively,and has provided theory model and technical ways for ground target recognitions under infrared countermeasure conditions.
