Description

technical field [0001] The invention relates to a nuclear explosion electromagnetic pulse signal generation method and device, in particular to a pulse source capable of generating a standard high-altitude nuclear explosion electric field waveform in a TEM cell, which is used for electric field probe calibration and small key components for anti-nuclear Electromagnetic reinforcement experiment. Background technique [0002] The electromagnetic pulse field strength produced by the nuclear explosion is extremely high, the rising edge is steep, and the spectrum is wide. Especially when the explosion height exceeds 30 kilometers (called high-altitude nuclear explosion electromagnetic pulse), the radius of the projected point of the explosion center will be hundreds of kilometers or more. Various military and civilian electronic information systems and power systems within the range pose a serious threat. With the wide application of various electronic sensitive equipment in var...

AI Technical Summary

Problems solved by technology

This kind of pulse source is generally used in larger simulators, but its technical difficulty is relatively high, the investment is high, and the operation and maintenance costs are high.

Moreover, most of the nuclear electromagnetic pulse simulators that have been built are simulation devices that generate a single waveform, especially the simulators used for the calibration of field strength probes do not yet have the function of multi-waveform output.

At the same time, the small pulse source with an output voltage of about 10kV does not use a vacuum relay as a discharge switch to achieve rapid conduction of the circuit.
