机载红外探测仪检查搜潜建模与仿真

Modeling and simulation for checking search submarine by airborne infrared detectors

依据经典的检查搜潜方法,结合实际的搜潜过程,以某型反潜巡逻机为背景,建立了反潜巡逻机执行平行航线搜潜、外旋扩展方形搜潜和内旋扩展方形搜潜时航路规划的数学模型和潜艇运动模型。对3种检查搜潜方法的搜潜效能进行了分析,并对初始距离、搜潜海域面积、潜艇经济航速和海洋大气环境对检查搜潜效能的影响进行了仿真。实验结果表明:初始距离的变化对搜潜效能影响很小,而搜潜海域面积、潜艇经济航速和海洋大气环境的变化对搜潜效能影响较大;相同条件下,使用平行航线搜潜,获得的搜潜效能最高。

According to the classical checking search submarine means,and combining the actual process of submarine search,the mathematical models of route planning such as parallel line pattern search,outward spiral extended square pattern search,inward spiral extended square pattern search and submarine moving models were built against the background of some antisubmarine patrol aircraft.Moreover,the search submarine efficiency of the three means were analyzed,and the influences of the initial distance between the submarine and the antisubmarine patrol aircraft,the search sea area,the submarine economical speed and the sea atmospheric environment on the search efficiency were simulated.The results show that the initial distance has little effect on the first three models mentioned above,while the search sea area,the submarine economical speed and the sea atmospheric environment have a great effect on the three models under the same conditions.The best search efficiency can be obtained by using parallel line search under the same condition.
