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 TR 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 TR 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.
