ABSTRACT:
A system and method for controlling the times of activation and deactivation of transmit amplifiers, receiver amplifiers and receiver protectors of multiple T/R modules during successive transmit and receive cycles of an active aperture phase array antenna of a radar system. The corresponding elements of each T/R module are delayed to operate like elements simultaneously. The delayed application of this T/R signal to the like element is varied for operating unlike elements of the array at predetermined times relative to one another. A system and method for determining the required delay is disclosed.
