单架机载预警雷达探测目标时存在空域覆盖盲区和多普勒盲区。建立了巡逻航线的参数化模型,推导了机载预警雷达目标发现概率计算模型;提出了基于累积发现概率矩阵2-范数的单架机载预警雷达巡逻航线优化准则。由于多架机协同可以减小盲区对探测性能的影响,进一步研究了多架机协同探测的任务航线规划问题,提出了优化准则,分析了机载预警雷达之间的飞行时间间隔和航线之间的距离间隔对重点监视区域累积发现概率的影响。仿真结果表明了基于累积发现概率矩阵2-范数的优化准则的有效性,有利于最大化机载预警雷达空域覆盖和目标发现概率。
There is airspace coverage blind spot and Doppler blind spot in the single target airborne early warning radar detection target. The parameterized model of patrol route was established and the calculation model of target discovery probability of airborne early warning radar was deduced. An optimization criterion of patrol route for single carrier airborne early warning radar based on cumulative probability matrix 2-norm was proposed. The multi-aircraft cooperation can reduce the impact of blind zone on the detection performance, and further study the mission route planning problem of multi-aircraft collaborative exploration, propose optimization guidelines, analyze the flight time interval between airborne early warning radar and the route between Of the distance between the key surveillance area cumulative probability of discovery. The simulation results show that the optimization criterion based on 2-norm of cumulative probability matrix is effective, which is beneficial to maximize the space coverage and target discovery probability of airborne early warning radar.
