摘要
针对航空集群独立反隐身的任务需求,提出使用集群任一成员机载雷达作为发射阵元,群内其他成员机载雷达作为接收阵元,构建多部双基雷达,利用雷达收、发分置带来的空间分集优势,在隐身目标不同方位探测其散射的电磁波,形成反隐身能力。研究了接收节点在不同距离和方位配置时形成的反隐身探测空域;针对机载雷达扫描角限制造成的前向空间探测盲区,提出了3种集群飞行器机动策略。仿真结果表明,航空集群各节点均能够形成一定的反隐身探测能力,不同集群构型能够适应不同威胁等级的反隐身任务需求;发射节点通过S形机动能够达成良好的雷达补盲效果。
To meet the demand of aircraft swarm autonomously anti-stealth, a bistatic airborne radar system concept is proposed, where the airborne radar of any member in the aircraft swarm can be designed as bistatic radar transmitter while the others are designed as the radar receivers. Benefiting from the space diversity design, the swarm members can detect the scattered radar electromagnetic energy from different directions of the stealth target and find out the stealth aircraft. Based on this concept, this paper calculates the anti-stealth airspace range of the bistatic airborne radar system when the radar receivers are placed at different distance and different direction. To eliminate the blind area caused by the radar scanning angle in the swarm forward detecting airspace, three basic types of maneuver strategies of the swarm aircrafts are put forward. The simulation results indicate that, all the radar nodes in aircraft swarm can possess the anti-stealth ability but of various detecting area size and shapes, and different swarm configuration suits different anti-stealth needs in different threat level airspace. The strategy that keeps the radar transmitter node flying in S-type way can fill the swarm detecting gaps.
