Technique for roll stabilization and partitioning of phased array antenna receiving apertures

Abstract From the Canadian patent

An active array system is disclosed with electronic roll stabilization of the difference patterns and with, arbitrary partitioning of the phase scanned aperture with no hardware changes. The array system comprises a large number of radiating elements forming the array with, individual transmit/receive active modules coupled to each radiating element. In each active module the received, signal is amplified and then divided into three signal components. Two of the signal components are passed through a bi-state phase shifter for selectively phase shifting the signal component by 0 to 180 degrees. The selectively phase shifted receive signals are then coupled to the respective azimuth and …
