ABSTRACT:
An apparatus and method for identifying sidelobe transmitted and/or received radar signals. The apparatus is utilized in a radar system having a transmitter for generating at least one detection signal, an antenna system defining a mainbeam and sidelobe radiation pattern for transmitting each detection signal and for receiving electromagnetic signals including echo signals each corresponding to a reflection from an object of a transmitted detection signal, and a receiver system for processing each received echo signal. The apparatus is embodied as a system for identifying each echo signal received upon the antenna system sidelobe and each received echo signal having a corresponding detection signal transmitted on the antenna system sidelobe. The system comprises a modulation system for modulating each sidelobe radiated detection signal and each sidelobe received echo signal; and a detector system for, receiving from the antenna system each echo signal, identifying each echo signal having the modulation and providing an indication signal for each echo signal having the modulation.
