ABSTRACT:
An architecture for a monopulse, active aperture array is provided which functions as a high precision error compensation system correcting both the Sum and the Difference beams simultaneously. The architecture incorporates; a radiating antenna, a transmit-receiver, a -3.01 dB Wilkinson divider operable to split the signal received from the transmit-receiver, a Sum plus Difference network, a Sum minus Difference network both of which accept the split signal from the -3.01 dB Wilkinson divider and simultaneously error compensate the beams, and a four port magic tee operable to output the error compensated signals from the Sum plus Difference network and the Sum minus Difference network.
