An improved system is disclosed for controlling the operation of a transmit/receive module in a phased-array antenna system. The improved module control system of the invention is implemented in a simple integrated circuit chip and may be co-located with a transmit/receive module positioned at an antenna array element. Either fully distributed or row/column distributed beam steering architecture may be implemented by the improved module control system with both speed of operation and cost advantages realized over prior art systems.

Integrated module controller

A Doppler matched binary pulse compressor having means to initiate operation, means to generate a Doppler matched filter bank, means to compress the pulses from the Doppler matched filter, either linear or soft limited, means to estimate the signal phase in real time and means to select overall optimal filters in real time. The foregoing includes a phase estimator having a quadrant detector and means to scale the quadrature components while preserving the signal phase, means to reduce accuracy computations to 45.degree. or less of the first quadrant, and means to reconstruct the phase to place the signal in the proper quadrant.
