For a cognitive radio communication system coexisting with radar to access the radar spectrum opportunistically, an efficient Cooperative Sensing Algorithm (CSA) for swept radar pulse train is proposed. There is a central processing node which cooperates with other sensing nodes to sense a radar spectrum channel. Moreover, the similarity judgment of the single node and data fusion based on time-series identification of the central processing node can greatly improve the probability of detection and reduce the probability of false alarm. Compared to existing methods of sensing radar signal, the proposed algorithm can quickly and reliably detect swept radar pulse train without any prior information on the radar. At the same time, the radar parameters, such as rotation period, scanning direction, distance etc., can be acquired. Finally, simulation results show the effectiveness and correctness of the algorithm.
