反潜巡逻机雷达巡逻搜潜的面积等效模型

Radar Patrol Searching Area Equivalent Model of Antisubmarine Patrol Aircraft

针对反潜巡逻机使用雷达巡逻搜潜问题,首先给出了雷达搜索概率模型,不仅分析了雷达搜索扫描宽度,而且综合考虑了潜艇是否暴露、能否规避两个重要因素。在此基础上,通过分析反潜巡逻机巡逻线阵位、相对运动关系,采用面积等效法,建立了适用于一般情况的巡逻搜潜探测概率模型。最后,仿真分析了搜索时间、巡逻线长度与阵位位置等因素对雷达探测概率的影响。结果表明,面积等效模型可较好地解决反潜巡逻机巡逻搜潜的概率计算问题;反潜巡逻机使用雷达巡逻搜潜时,发现概率随搜索时间的延长而增加,但最后趋于一定值,且最大发现概率不高。

To the patrol searching problem of antisubmarine patrol aircraft using radar, a radar searching probability model was presented, which considered the scanning width of radar searching, the submarine exposure rate and detection avoidance rate. Based on this, through analyzing the patrol line station and relative movement of antisubmarine patrol aircraft, a general patrol searching detection probability model was built up by adopting area equivalent method. Finally, the influence of searching time, length and station position of patrol line on radar detection probability was analyzed by simulation. The results showed that ： 1 ） the area equivalent model can better solve the patrol searching probability calculation problem of antisubmarine patrol aircraft, and 2） the radar detection probability increases with the searching time, but it tends to a special value, and the maximum detection probability is not high.
