ABSTRACT:
1. A system for radiating recurrent pulsed signals having a variable carrier frequency, said system comprising: a source of signals having a random voltage: a non-linear amplifier coupled to said source for amplifying said signals and providing amplified signals, said amplifier having a gain which decreases upon the amplitude of said signals exceeding a predetermined absolute value and having an output; means coupled to said output of said amplifier for storing an amplified signal for the duration of each recurrence period of said pulsed signals; and variable frequency, voltage controlled oscillator means coupled to said storing means.
