V. Read and translate the text: Text 3a Radar Signal Categorization Using a Neural Network

We have used neural networks to cluster, characterize and identify radar signals from different emitters. The approach assumes the ability to monitor a region of the microwave spectrum and to detect and measure properties of received radar pulses. The microwave environment is assumed to be complex, so there are pulses from a number of different emitters present, and pulses from the same emitter are noisy or their properties are not measured with great accuracy.

For several practical applications, it is important to be able to tell quickly, first, how many emitters are present and, second, what their properties are. In other words time average prototypes must be derived from time dependent data without a tutor. Finally the system must tentatively identify the prototypes as members of previously seen classes of emitters.
