摘　　要：草地地表的温度是仿真其红外热像图的关键,综合考虑太阳辐射、风速、大气温度和空气相对湿度等因素的影响,建立了草地地表的温度计算模型,利用C++语言编程计算出草地地表不同时刻的温度,从而求出红外辐射亮度,并进行红外热像图仿真,仿真结果表明:该模型和方法能够真实地生成草地地表的红外热图像,可广泛应用于红外场景仿真中。The surface temperature of grassplot is the key factor of thermal image simulation. Comprehensively considering influence of such factors as radiation of the sun, wind speed, atmospheric temperature, relative air humidity and so on, the temperature calculation model of grassplot is established. The surface temperature of grassplot at different time is calculated with the C++ program, and the infrared radiance is obtained. Then the infrared thermograph is simulated. The simulation results show that the model...
