  • Surveillance radar system which is protected from anti-radar missiles
    Patent number: 4538152
    Abstract: A surveillance radar system comprising an omni-directional transmitter and a number of radar receivers located at different geographic locations from the transmitter which are capable of resolving the angular location of targets by using antenna lobe multiples over the range to be monitored so that anti-range missiles cannot destroy the receivers since their locations will be unknown. The transmitter transmits on a continuous basis rather than on pulsed basis to reduce the probability of location by anti-radar missiles.
