In this paper,a cascaded model consisting of associative memory and WTA model which are cascaded is used to the recognition of multiplex target with spatial ratation.In order to utilize the time and spatial band product,A fully unipolar model,which neural states and interconnection weights are postive,is constructed.To covercome the difficulty of implementation in optics,the interconnection weights with gray levels is binarized by uaing adaptive clipping method.The performance of the cascaded model is simulated by using four kinds aircraft.
