| Abstract: | This paper deals with design principles,development and performance of a field measurement instrument for nuclear electromagnetic pulse(EMP) based on signal transmission through fiber.To determine the minimum band width this instrument needs,we analyze cutoff spectrum of a time domain double exponential signal,employing Fast Fourier Transform(FFT),and get its inverse transform signal.Then we design the circuit of laser device and the circuit of measuring device according to previous analysis.This instrument meets requirements of related regulations.Its specifications meet requirements of NEMP hazard protection research and can be of great significance to it. |
