Pulse generation device

摘要

Provided is a pulse generation device capable of suitably adjusting and outputting a pulse pattern by a simple configuration. A pulse generation device (100) includes a radio frequency oscillator (110) that generates a carrier wave of a certain frequency, a baseband pulse generating unit (120) that generates a signal having a certain pulse shape at a baseband, a timing generator (130) that controls a timing to generate a pulse through the baseband pulse generating unit (120), and a mixer (140) that modulates the carrier wave output from the radio frequency oscillator (110) using the pulse output from the baseband pulse generating unit (120). The timing generator (130) can adjust a waveform of the pulse output from the baseband pulse generating unit (120).

1. A pulse generation device, comprising:
baseband pulse generating circuitry including a pulse generator that generates a pulse train including two or more monopulses and a low pass filter that receives the pulse train output from the pulse generator and outputs a baseband pulse signal, wherein the pulse generator generates the pulse train based on a certain control signal adjusted so that the baseband pulse signal has a certain pulse waveform which does not exceed a certain limited range, the pulse train includes a main pulse including a main monopulse having a first pulse width and one or more monopulses having a pulse width smaller than the first pulse width, the one or more monopulses being generated ahead of or behind the main monopulse on a time axis, and the one or more monopulses having the smaller pulse width have a frequency component of a cut-off frequency of the low pass filter or higher.
