摘　　要：针对雷达集群协同探测问题,提出一种单次快拍协同成像方法。由雷达集群的中控节点根据探测场景选定发射节点,发射节点发射宽带电磁波并向其他节点发送同步时间戳;其他各节点收到同步时间戳后,接收被测区域的散射回波并进行回波处理;集群中除中控节点之外的各接收节点向中控节点传输数据;最后由中控节点进行成像处理。对雷达集群网络进行仿真验证,证实了该方法的可行性。In order to solve the problem of cooperative detection of radar swarm,a single snapshot cooperative imaging method is proposed.Firstly,the central control node of radar swarm selects transmitting node according to the detection scenario.Then the transmitting node transmits broadband electromagnetic wave and synchronization time stamps to other nodes in the swarm simultaneously.After receiving the synchronization timestamp,other nodes of swarm accept the scattered echo and performs echo processing.Each receiving node in swarm except the central control node transmits data to the central control node.Finally,the imaging process is performed by the central control node to obtain the cooperative imaging result of radar swarm.The simulation verification of the radar swarm network confirms the feasibility of this method.
