| 摘 要： | 通过外场实验,研究了在阴天光照条件下,探测角、方位角、探测波段等因素对深绿色、浅绿色伪装涂层和草地偏振度探测结果的影响.结果表明:在阴天光照条件下,伪装涂层偏振度的探测结果主要受探测角和探测波长的影响较大,受探测方位角的影响较小;而探测角、探测波长以及探测方位角的变化对草地偏振度的探测结果影响不大,草地的偏振度始终保持在0.1左右.因此,合理地选择偏振成像探测条件可以使伪装涂层与草地之间的偏振度存在较大差异,利用该差异可以对传统伪装涂层涂覆的目标进行有效地探测和识别,因而偏振成像探测技术具有重要的军事应用价值.

| Abstract: | To study the effect of detection angle,azimuth angle and wavelength on polarization degree of grassplot,bottle green and aqua camouflage coatings were measured in the field under cloudy condition.Experimental results showed that the polarization degree of camouflage coatings were rather more influenced by detection angle and wavelength than by azimuth angle;and that these three factors above had a little effect on polarization degree of grassplot with a constant value of 0.1 around.Consequently,choosing pro... |
