Stephen Robinson’s contribution to electronic engineering lies in the field of broadband microwave circuits, techniques and systems. He is responsible for a number of important innovations related to electronic countermeasures incorporated in the defence systems of a number of countries. Of particular merit has been his invention of instantaneous frequency measuring techniques.
His octave-bandwidth microwave hybrid junction has found application in the design of mixers, single sideband modulators and phase discriminators required for applications such as multifrequency radars. His digital phase-measuring techniques have led to improvements of several orders in the performance of frequency discriminators. They have been incorporated in a microwave digital guidance system (MADGE) — the first integrated surveillance/navigation/communication system for aircraft — and are operational in Harren aircraft. For this work, Stephen received the Royal Society’s S. G. Brown Award.
Stephen served as Product Director of MEL and Managing Director of Pye TVT. He also served several defence science committees. Since retirement in 2001 as Director of the Royal Signals and Radar Establishment, Malvern, he has been concerned with engineering standards at the IET.
