Random Look-Through for Jamming Transmitters
Abstract
"Look-through" methods, as used in countermeasures transmitters have been investigated to find a means of improving the operation of the transmitter and reduce the time required to obtain satisfactory "look-through." The ideal system would include look-through simultaneously with the jamming. Because of the wide frequency range which modern countermeasures transmitters are required to cover, such systems would require almost constant adjustment by an operator. Time-sharing "look-through" was investigated and it was found possible to cut off a 1-kw magnetron by electronic means. A system has been developed for the generation of randomly tuned pulsers to give look-through at a random rate, making it difficult for the enemy to evade being jammed by deliberate synchronization of the radar pulse repetition frequency (PRF) with the look-through period of jammer. Such a system has the advantage that it is not limited to a particular radio-frequency range.
