Abstract:

A computer technique is described which efficiently implements the NEL Sonar Contact Classification System. The correct output is determined by a logical product method rather than by the usual table storage and look up methods. The computer gets its inputs from a keyset designed specifically for sonar classification. The contact classification given by the computer will be identical to that made from tables based on the current NEL Sonar Contact Classification System for scanning sonars. A logically identical technique turned out to have an application within the NELIAC compiling program, where it was reported to save 13 of the compiling time. The success of the method in these two applications led to some examination of the general usefulness of the method as a substitute for table storage and table look up in computer programming. One type of problem where this method should be efficient is the making of decisions in real time systems, where the decisions are based on the existing values of several variables. Author
