Coupled oscillator based agile beam transmitters and receivers: a review of work at JPL

摘要: This is a review of the work done at Caltech's Jet Propulsion Laboratory during past decade on development coupled oscillator technology in phased array applications to spacecraft telecommunications. First, some historical background provided set context. However, this by no means intended be comprehensive all area. Rather, focus JPL contribution with mention other which either insight or motivation. In mid 1990s, R. A. York, and collaborators proposed that an mutually injection locked electronic oscillators could provide appropriately signals radiating elements antenna such radiated beam steered merely tuning end perimeter array. et al. also receiving system based arrays properly local mixed received remove phase due angle arrival incident wave. These concepts were viewed as promising simplification steering control result significant cost, mass, prime power reduction therefore attractive for possible space application. The initial was largely theoretical and, collaboration York Maccarini, Pogorzelski developed linearized formulation analysis considerable into dynamic behavior aperture function tuning. key results (and limitations) their implications performance are reviewed here. Subsequently, several experimental designed, fabricated, tested. described salient outlined. body has brought from mere awareness concept ago, through transmitters receivers concept, brink current effort integrate transmit receive functions single unit future fight
