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.

Abstract: An apparatus for measuring a comprehensive state of vector displacement between a group of at least two pairs of longitudinally spaced side-looking radar arrays mounted upon a flexible host vehicle. This apparatus will operate to measure in three linear translation motions and three rotational motions, the relative positions of the radar array antennas upon the host vehicle during maneuvers of the host vehicle.
