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。

Airspace covering blind area and Doppler blind zone occur as single airborne early warning (AEW) radar is operated to probe targets. The parameterized mathematical model of AEW radar patrol routes was established. The calculation formula of AEW radar target detection probability was derived. And the patrol routes optimizing criterion of single AEW radar was proposed based on the 2- norm of accumulated detection probability matrix. The mission routes programming problem of multi- AEW radar cooperation probing was studied further and the optimizing criteria was presented in that multi- AEW radar cooperation can help reduce the bad influence of airspace covering blind area and Doppler blind zone on detection performance. Finally, the effects of time interval and distance separation between AEW radars on accumulated detection probability of the key surveillance area were analyzed. Simulation results show that the optimizing criteria founding on 2- norm of accumulated detection probability matrix are effective which are conducive to maximize the coverage and target detection probability of AEW radar.
