基于探测概率的雷达网反隐身开关机模型

The Model of Opening/Closing Radars for Radar Network Anti-Stealth Based on Detection Probability

为提高雷达网对隐身目标的战术对抗能力,根据隐身飞机的特点,提出主战方向角概念。由主战方向角和雷达与目标的相对位置来计算雷达对隐身目标的探测概率。按照隐身目标航迹经过的每个网格,建立了基于探测概率的雷达网开关机模型,并在每个网格内选取主战雷达和助战雷达。仿真结果表明,该模型可以快速准确地评估雷达网搜索目标的能力,并为指挥员对雷达网内各部雷达进行有序的实时指挥提供有价值的参考。

In order to improve the anti-stealth ability of radar network, based on the character of stealth aircrafts, the main fighting orientation angle conception is put forward in the paper. Based on the main fighting orientation angle and the relative position of radars to targets, the radar detection probability of detecting the targets can be calculated. According to every grid that the flight paths of targets passed by, a mathematic model of the opening/closing radars is presented, based on the detection probability and choosing of main fighting radar and assistant fighting radar in every grid. Simulation results indicate that the model can quickly and accurately evaluate the ability of searching targets of radar network, and it also supply some advises for the commanders to control each radar in radarnet timely.
