Electronic warning and camouflage installation - uses decoy installation(s) at set distance from radar installation with directional aerial system protecting pulse transmitter from enemy missiles

摘要

The arrangement for electronic warning and concealment of a pulse transmission installation (1) from energy missiles(2) uses passive sensors amt. a pulse edge scanning circuit in order to search a given zone of the sky, according to received e.m. pulse signals. The pulse edge scanner circuit contains a time 'window' of given width (Tau) which determines the signal discrimination time, amts. derives signals in a signal processing circuit for target-search focussing. The pulse transmission installation is e.g. a radar installation (1) for air-space surveillance, and includes a transmission and reception unit, or in other arrangements an alert (warning) radar installation for ascertaining the speed and location of incoming missiles. A deception transmission installation conceals the presence of the radar equipment. ADVANTAGE - Mobile installation facility.
