Abstract

The invention relates to the field of high-power microwaves, and provides an ultra-narrow pulse generation device combined feeding device and an ultra-narrow pulse generation device combined feeding method for solving the problem existing in the prior art. The ultra-narrow pulse generation device combined feeding device and the ultra-narrow pulse generation device combined feeding method improve the energy conversion efficiency and high-repetition-frequency output power of an ultra-narrow pulse source based on an avalanche transistor, and provide a better solution for arrayed application. According to the ultra-narrow pulse generation device, the time that a power supply end high-level signal is ahead of an ultra-wideband narrow pulse voltage signal is greater than the complete resonant charging time of an arbitrary stage RC charging loop; an ultra-wideband narrow pulse voltage Vf is input to one end of a first stage energy storage capacitor which is away from a second stage energy storage capacitor, a first stage avalanche transistor circuit discharges, and an output voltage value of an output end of a first stage avalanche discharge loop is Vf+V without considering circuit loss; and an output voltage value of an output end of an i stage avalanche discharge loop is Vf+i*V.

Description

technical field [0001] The invention relates to the field of high-power microwave (HPM), in particular to an ultra-narrow pulse generating device composite feeding device and a method. Background technique [0002] The ultra-narrow pulse signal has a very short duration and a wide spectrum width, which theoretically will interfere with all current electronic systems. The ultra-wideband radar (carrier-free radar) using ultra-narrow pulse signals has advantages that conventional radars cannot match, such as high distance resolution, low intercept probability, anti-stealth, anti-jamming, anti-anti-radiation missile, and strong penetration. . [0003] At present, a class of ultra-narrow pulse sources based on avalanche transistors (hereinafter referred to as avalanche transistors) can provide 10kHz-level repetition frequency, ns-level pulse width, kV-level output voltage amplitude, 100ps-level rising edge and 10ps-level leading edge jitter , and has the characteristics of smal...
