摘要
随着红外探测与制导技术的飞速发展,对于舰船红外特征的研究具有越来越重要的军事意义。在简化舰船动态传热模型的基础之上,模拟出舰船表面瞬时温度变化与目标辐射强度的周向分布结果。模拟结果表明舰船的主要部位的表面温度在一天之中变化显著,且在同一时刻部位间的温度也存在明显差异;舰船不同时刻的辐射强度沿周向差异显著,同一时刻不同方位角上的辐射强度存在一定差异,同一时刻同一方位角上的辐射强度随仰角的增大而增大。
As the infrared detection and homing technology maturate daily,the study on infrared characterization of ship becomes more and more important. Based on the simplified heat transfer model ,the surface temperature changes and distribution of radiant intensity of ship were simulated. The results showed that the temperature of main parts of ship was different in a day, and it was also different among these parts at the same time. The radiant intensity was different around the ship at different time,and it was also different at the same time with different azimuth angle,and it increased with the increase in elevation angle.
