A nuclear explosion electromagnetic pulse signal source simulation device

Abstract

The invention relates to a nuclear explosion electromagnetic pulse signal source simulation device. The signal generation unit of the present invention is realized by a digital circuit, that is, DSP+DDS is used to form the main circuit of the signal source simulation device, and the setting and control of the DDS by the DSP are realized through the SPI interface. The crystal oscillator is the DSP clock input, and the DSP system clock output signal is used as the DDS clock input. The DSP sets the DDS internal PLL through SPI communication to control the DDS system clock frequency, and then can achieve 300MHz~30MHz frequency conversion output. DDS can obtain a maximum output signal of 400MHz. The frequency conversion period is adjustable, and the minimum frequency conversion period is 4ns; the amplitude is adjustable, which is suitable for simulating the electromagnetic pulse signal of the nuclear explosion electromagnetic pulse in the atmosphere and the longitudinal transmission through the ionosphere, especially for the simulation of the electromagnetic pulse signal of the nuclear explosion in the satellite detection nuclear explosion signal test , is of great significance to the national defense construction of our country.
