  • 深空背景中机动目标光谱辐射探测是目标机动模式和属性识别的重要研究内容.基于光谱散射和辐射理论,首先建立了复杂背景环境中目标反射背景辐射分布函数,然后根据气动加热引起的目标蒙皮温度场分布情况,建立了角水平和角俯仰的目标本征光谱辐射模型;结合空间目标运动方程和目标本体坐标系与探测器坐标系之间的旋转关系矩阵,重点分析了目标不同机动模式下光谱响应信号的时空过程性变化特点.仿真实验结果表明,探测器中的光谱响应信号因目标时空域的变化而呈现不同的特点,说明了目标机动模式与光谱响应信号间存在显著的特征映射关系,这为解决目标运动模式可分性问题提供了可行性,同时得出了目标姿态和空域相对位置是影响光谱响应信号特征的主要因素的结论.
    Spectral radiation detection in deep space background is an important fundamental research in the field of infrared target detection and identification. Based on the spectral radiation and scattering theory, the spatial distribution model of aerial target reflecting background radiation under complex environment is first built. Then the horizontal and pitch spectral radiation models of target are built based on target skin temperature distribution caused by aerodynamic heating. Combining the target motion equation and relative rotation matrix between target matrix and detector matrix, the process-oriented characteristic of spectral response signal with spatiotemporal variation is emphatically analyzed. The simulation results indicate that different target maneuver modes cause different characteristics of spectral response signal, which shows that a remarkable mapping relationship exists between the target maneuver mode and spectral response signal characteristic. Thus using the spectral response signal to identify target maneuver mode provides a feasible method, and the target posture and relative position are the main factors to affect the spectral response signal characteristic.
