Abstract

The invention provides a bounded wave intensity electromagnetic pulse simulation system. The system comprises a high-voltage pulse assembly and a waveguide type antenna connected with the high-voltagepulse assembly, wherein the tail end of the waveguide type antenna is connected with a load; the high-voltage pulse assembly comprises a direct-current high-voltage module, a charging resistor, an energy storage capacitor and an air switch which are connected in sequence, the capacitance value of the energy storage capacitor is adjustable, the air switch comprises a shell, and a first electrode and a second electrode with variable discharge gaps are arranged in the shell and filled with working gas with variable pressure intensity; the direct-current high-voltage module is used for outputtingdirect-current high voltage and compressing the direct-current high voltage into the energy storage capacitor through the charging resistor, the energy storage capacitor is used for triggering the air switch to be broken down to form corresponding voltage pulses, and the voltage pulses are transmitted to a load through the waveguide type antenna. Strong electromagnetic pulse amplitude, leading edge and pulse width output by the system are large in variation amplitude and small in dispersion degree, and the stability of the system is high.

Description

technical field [0001] The invention relates to the field of electromagnetic field technology, in particular to a bounded wave strong electromagnetic pulse simulation system. Background technique [0002] The high-altitude nuclear electromagnetic pulse (HEMP) effect test is a test that places the subject in the HEMP environment, studies its effect law, and evaluates its combat effectiveness and survivability in the HEMP environment, usually in an artificially simulated radiation environment. next. At present, domestic common HEMP simulators include radiation wave simulators and bounded wave simulators, which are composed of high-voltage pulse sources, transmission lines and terminal loads. The bounded wave simulator (also known as the guided wave electromagnetic pulse simulator) uses a parallel plate transmission line as its antenna, and the electromagnetic wave propagates along the parallel plate transmission line, mainly in the TEM mode. During the propagation of electro...
