海面复杂红外场景仿真系统

摘要

针对红外成像反舰导弹导引头视景的仿真问题，建立了海面复杂红外场景计算机仿真生成系统。对于视景的空间参数，首先给出仿真在用于描述空间关系的坐标系的定义以及它们之间的关系，然后分别分析了物体和背景的空间参数解算策略；对于场景的红外特性，从各个物体的红外特性、海面背景红外特性以及大气红外特性三个方面进行讨论。最后，给出整个仿真系统的运行流程。实验表明，该仿真系统能够有效的实现海面复杂场景的仿真，可以用于与红外成像反舰导弹相关的仿真研究中。%It is proposed a complex infrared scene simulation system which can simulate the scene of the seeker of IRimaging guided anti -ship missile on the sea surface.For the spatial parameters of the IR scene,firstly the coordinatesystems for describing the spatial information and their relationship are introduced.Then the strategy of calculatingboth the objects′and background′s spatial parameters is discussed.The IR characteristic of the simulated scene is an-alyzed,including the IR signature of different kinds of objects,sea surface background and atmosphere.Finally theprocess of the whole simulation system is presented.Experiment shows that the proposed system can effectively simu-late the complex infrared scene on the sea surface,and it is proper for the study related to IR imaging guided anti-shipmissiles.
