Title: Method for generating high-power short microwave pulses
Inventor: SERGEEV V I
IPC: H03K12/00
Filed: 2002-05-13
Granted: 2003-08-20
Abstract: FIELD: microwave engineering. SUBSTANCE: method includes excitation of low-power microwave signal, amplification, and modulation of microwave signal. Low-power microwave signal is excited in the form of sine- waveform microwave carrier at frequency f 0  and phase φ 0  which is modulated either by frequency keying for which purpose its frequency is discretely varied obeying f 0 , f 1 , f 0 , f 1 ..., law or by phase keying through discrete variation of its phase obeying φ 0 , φ 1 , φ 0 , φ 1  law, or else by frequency and phase keying involving variation of its frequency and phase obeying (f 0  and φ 0 ), (f 1  and φ 1 ), (f 0  and φ 0 ), (f 1  and φ 1 )..., law; in the process lifetime of modulated signal in the form of wave with f 0  frequency and φ 0  phase indicates pulse length and lifetime of modulated signal with carrier wave frequency f 1 ≠ f 0  and/or phase φ 1 ≠φ 0  shows pulse-to-pulse space length, where f 0  and φ 0  are constants and f 1  and/or φ 1  are constants or variables; then signal is selected at carrier wave frequency f 0  and phase φ 0  by frequency and/or band filtering of modulated microwave signal, whereupon signal obtained is amplified and filtered again to select high-power signal at carrier wave frequency f 0  and phase φ 0 . EFFECT: reduced on-off time ratio of high-power short microwave pulses produced. 3 cl, 5 dwg
