Abstract: A protection device for a pulsed radar system which generates a random pu train whose pulse spacing is kept between a predetermined maximum and minimum. A jitter coder alters the periodic timing of the clock pulses fed to the radar modulation circuit by means of a jitter code generated by a jitter code generator. The reflected radar signals are decoded in a decoding circuit using the jitter code generated by the jitter code generator.
