| 摘要: |
| 合理规划网络化机载雷达的运动航迹，能够减小其重复搜索区域，提升区域搜索效率。针对战场侦察需求，提出了一种面向区域搜索的机载组网雷达航迹优化方法，以期在给定的时间内完成更大范围的侦察搜索。结合雷达方程表征了单平台搜索范围，并基于栅格化思路计算了多雷达区域覆盖函数。以最大化搜索覆盖函数为目标，结合各节点运动约束，构建了航迹优化模型，并利用智能化方法对其进行求解。仿真结果显示，所提出方法能在给定的时间内获取更高的搜索覆盖率。 |

| Abstract: |
| Reasonable planning the trajectory of the airborne radar network can decrease its repeated surveillance region, and improve the search efficiency. To complete a wider range of reconnaissance searches within a certain time, a search task oriented path optimization method of airborne radar network is proposed. Firstly, the single-platform search range by combing the radar equation is characterized, and the multi-radar area coverage function based on the rasterization idea is calculated. A trajectory optimization model with the goal of maximizing the search coverage function is constructed, by combining with the motion constraints of each node and adopting an intelligent method. Simulation results show that the present method can obtain higher search coverage within specified time. |
