DEVICE FOR GENERATING HIGH-POWER BROADBAND PULSED SIGNALS ACROSS REFLECTOR-TYPE ANTENNA ARRAY Russian patent published in 2006 - IPC H01Q21/29 

FIELD: radio and radar engineering; devices using radio pulse trains.

SUBSTANCE: proposed device has scanning antenna incorporating coherence frequency spectrum shaper and radiating components, reflector-type phased antenna array incorporating reradiation components, controlled phase shifters, and short-circuited delay lines wherein inputs of reradiation control components are connected to outputs of controlled phase shifters; control inputs of the latter are connected to outputs of phase-shifter control system; inputs of phase shifters are connected to outputs of short-circuited delay lines; scanning antenna forms reflector-type phased-array feed; short-circuited delay lines are designed to compensate for difference in time of occurrence of feed signal maximum across adjacent reradiation components; this time τ_d = d/(V_sR), where d is distance between adjacent reradiation components; V_s is directivity pattern scanning rate; R is distance from scanning antenna.

EFFECT: enhanced pulse power being radiated.
