METHODS FOR CALCULATING AND ANALYZING INTERROGATION REPETITION FREQUENCY SETS NONSYNCHRONOUS FOR n INTERROGATIONS.

Abstract

A simple means of using a computer to determine sets of nonsynchronous interrogation repetition frequencies was devised and is presented along with some tables of results. When nonsynchronous interrogation repetition frequencies are used, the interrogations from any interrogator can experience no more than one interference per scan from the interrogations transmitted by any other interrogator. Thus, if k interrogators are beamed toward the same transponder, the interrogations from each can experience at most k - 1 interferences per scan. Application of this principle to beacon systems should eliminate lost targets caused by synchronous interference between interrogations. (Author)
