Abstract: The purpose of reconnaissance system’s information processing is signal recognition，which is also a key step in whole process of radar reconnaissance information processing.In order to solve the problem of radar signal recognition，a new type of recognition model is established which combines rough set and neural network closely in this paper.The model mixes the rough set’s strong rule extraction ability and the excellent classification ability of neural network.The simulation results illustrate the model reduces subject factors in signal recognition，improves network’s structure and can manage to identify radar signal without any transcendental information objectively and effectively.
