Abstract

В ходе данной работы, была проведена оценка существующих устройств, основанных на сверхкороткоимпульсных (СКИ) генераторах. Выбран СКИ генератор, разработанный в высшей школе прикладной физики и космических технологий. Принято решение в использовании нескольких СКИ генераторов для увеличения мощности передачи и формирования диаграммы направленности. Рассчитаны временные задержки, возникающие при перемещении сигнала по схеме. Разработана схема и печатная передатчика и приёмника. Получена осциллограмма сигнала с передающей части и проведена оценка его параметров. Объектом исследования является реализация СШП передатчика. Цель работы состоит в повышении энергетической эффективности СШП передатчика на основе разработки и внедрения СКИ генераторов. В результате исследований сформировано схемотехническое решение для реализации СШП передатчика и приёмника.

In the course of this work, an assessment was made of existing devices based on ultrashort pulse (SRS) generators. An SRI generator developed at the Higher School of Applied Physics and Space Technology was selected. The decision was made to use several SRS generators to increase the transmit power and form the radiation pattern. The time delays that occur when the signal moves according to the scheme are calculated. Designed circuit and printed transmitter and receiver. An oscillogram of the signal from the transmitting part is obtained and its parameters are evaluated. The object of study is the implementation of the UWB transmitter. The purpose of the work is to increase the energy efficiency of the UWB transmitter based on the development and implementation of SRS generators. As a result of research, a circuitry solution for the implementation of the UWB transmitter and receiver was formed.
