Abstract
A random number generator for generating a pseudo-random code for use with ittered pulse repetition interval radar systems has been disclosed in which the code generated by the random number generator possesses the five attributes desirable for a jittered radar PRI: a flat frequency spectrum, a nearly perfect spike for an autocorrelation function, a controllable absolute minimum and maximum interval, long sequences that do not repeat, and a reasonable average pulse rate. A method for analyzing the autocorrelation properties of the code generated by the random number generator is also disclosed. A means to generate a pulse signal with random pulse repetition jitter has been disclosed.
