异常折射环境下舰载雷达与光电探测性能的区划

Partition Method of Shipbased Radar/EO Detectability under Marine Abnormal Refraction Environment

针对海上异常折射环境下雷达微波与光波传播的差异,优化雷达/光电系统的有效配置,提出了利用常规海洋气象环境要素信息进行雷达光电探测性能的四种环境区划方法,其中基于海气温差(ASTD)和海气水汽压差(ASVPD)的划分规则更加直接和快速。通过海上试验数据分析,揭示了各划分区域的成因,证明了该项研究能够更好地发挥雷达/光电系统综合探测性能,提供及时准确的环境信息支持。

For the sake of the difference between the refraction character of EO/radar under anomalous refraction and two types of detection system＇s optimized disposition, the four types of partition method of EO/radar refraetion environment is raised based on ocean meteorology factors. The rule based Air-Sea Temperature Difference（ASTD） and Air-Sea Vapour Pres- sure Difference（ASVPD） is more direct and quick. The formative causation of partition area is expatiated through trial data analysis, which offer exact environmental information to the performance of radar/EO detection systems optimized synergy.
