Abstract : This paper is a follow-up to the one presented at the 1988 Antenna Applications Symposium where an Advanced Architecture for a monopulse active aperture array was presented. This architecture exploits the potential inherent in next generation T/R modules to reduce the number of elevation beamformers from three to two. The remaining two beamformers are relatively simple networks consisting of -3.01 dB Wilkinson Power Dividers, anti-symmetric in phase. This allows for simultaneous correction of the sum and difference beams with a single set of phase and amplitude controls found in the T/R modules. This paper describes the development of the conformal experimental hardware as it relates to a fuselage mount configuration. The architecture also compensates for conformal plane scan distortion by means of a single phase shifter located at the receive beamformer outputs.
