Pulse-Frequency Modulation

open access: yesIRE Transactions on Space Electronics and Telemetry, 1962
Pulse-frequency modulation (PFM) has been successfully employed as the encoding technique in a number of small U. S. Earth satellites where reduction of power and weight are prime considerations. This paper is concerned with the introduction of some of the more basic principles of PFM.

High Repetition Rate in Ultra-Wideband Radar Systems

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2016
Low and high repetition rate work modes for ultra-wideband radar are considered. The ultra-short pulse packs usage for ultra-wideband radar systems is proposed. The advantages, disadvantages and probable fields of usage of such method are shown.
