研究了海上异常折射环境对于雷达微波和远红外波段的影响,利用近海面大气折射环境数值模型以及福建平潭和西沙永兴岛的海洋环境观测数据对两个波段进行了对比。结果表明,当雷达微波出现负折射时,红外波段却出现“波导”超折射特征,但强度和厚度较弱;当微波出现大气波导时,红外波段多为负折射特征。该项研究可为复杂海洋大气环境下两种探测系统的优化配置以及海洋环境对舰载光电探测系统的影响研究提供科学参考。
The effects of anomalous refraction environment at sea on the radar microwave and far-infrared bands were studied. The two bands were compared using the numerical model of the atmospheric refraction environment near the sea surface and the ocean environment observations at Pingtan and Yongxing Island in Fujian Province. The results show that when the microwaves are negatively refracted, the “waveguides” super-refraction feature appears in the infrared band, but the intensity and thickness are weaker. When the microwave appears in the air waveguide, the infrared band is mostly negatively refracted. This study can provide scientific reference for the optimal configuration of two kinds of detection systems in complex marine atmosphere and the research on the influence of marine environment on the shipborne photoelectric detection system.
