Abstract : Research is presented on the feasibility of an electronic device capable of detecting and classifying moving targets by processing the audio output of battlefield surveillance doppler radars. The desired classification categories are personnel, vehicles, and natural clutter. To be feas ible such a device should come within practical limits of size and complexity and yield a performance which, when compared to that of human operators, would make its use desirable. Taken together with certain assumptions about how the device would be used and what operating speed criteria must be met, these requirements determined ground rules which have governed the conduct and scope of the work reported here. To judge the degree of success achieved by the program it is important, therefore, first to logically reconstruct the rational guidelines within which the program was conducted. (Author)
