Abstract

The technique of using three receiving elements for amplitude comparison monopulse direction finders (DF) is examined. An appropriate second-order discriminant function is chosen for this technique. Simulation is then used to compare the system performance to that of the two-element system. In performance evaluation, errors coming from receiver noise, antenna pattern, amplitude imbalance, and mechanical and quantization origins are accounted for
