坦克目标的红外成像建模与仿真

提出了坦克目标的红外成像建模方法.首先结合部位分解法和板块元法建立坦克目标的几何模型;其次根据传热学原理提出了坦克目标各部位的热平衡方程,进而得到相应波长范围内的红外辐射强度;接着根据导弹与坦克相对运动的特征建立了弹目时空交会模型;最后通过计算机仿真生成不同交会状态下坦克目标红外灰度图像.仿真结果表明,此红外成像模型是正确有效的.

Infrared Imaging Modelling and Simulation of A Tank Target

A method of infrared imaging modeling of tank target was proposed. Firstly, the geometric model of the tank target was established with the method of spot disassemble and plate atom. Secondly, the thermal equation of the different parts of tank was established on the basis of heat transmission theory, and the infrared radiation intensity within a certain wavelength range was acquired. The intersect model of missile-target in time and space was built up according to their relative motion characteristic. Finally, the infrared images of tank in various target-missile intersections were acquired by computer simulation. The simulation results show that the infrared imaging model is correct and feasible.
