深空背景下运动点目标探测距离模型研究

Research of Operation Range Model for Detecting Moving Point Target in Deep Space Background

红外相机探测运动点目标时,探测能力主要指标为探测距离,而影响探测距离的因素很多,如光学系统工作温度、红外探测器像元尺寸、目标特性等。文章从红外相机点源目标探测基本理论出发,建立了运动点目标红外相机探测距离估算模型,分析了影响探测距离的各相关因素,为深空背景下运动点目标红外相机的指标设计提供理论参考。

Operation range is the main technical parameter,which reflects the detection ability of infrared camera for detecting moving point target.The operation range can be affected by many factors such as the characteristics of the target,the parameters of the infrared camera and etc..Based on the spot target operation range classical theory,operation range estimation model for detecting moving point target in deep space is derived.The relational factors of estimation model are analyzed and researched,the results may help to analyze and design infrared camera.
