Abstract

The invention discloses a high-power microwave radiation field measurement device and method based on software radio. The device includes: a receiving antenna, an attenuator, a frequency converter, an A / D converter and a data terminal. The data terminal includes a receiving module, a software A detection module, a data processing module and an output module; among them, the receiving antenna, the attenuation link, the frequency converter, the A / D converter and the data terminal are sequentially connected in series; the receiving module in the data terminal is electrically connected to the A / D converter, and the receiving module , the software detection module, the data processing module and the output module are sequentially connected in series. The invented and designed L-band software detector has a sensitivity dynamic range of about 30dB, a detection voltage of 10mV-700mV, a response time of less than 1ns, high repeatability and stability, and is not affected by temperature and environmental electromagnetic interference.

Description

technical field [0001] The invention relates to the technical field of high-power microwave measurement, in particular to a software radio-based high-power microwave radiation field measurement device and method thereof. Background technique [0002] High-power microwave refers to strong electromagnetic radiation with a frequency range from 300MHz to 300GHz and a peak power greater than 100MW or an average power greater than 1MW. High-power microwaves have important applications in the fields of radar, communication, nuclear fusion heating, material processing, and directed energy. [0003] Radiation field measurement is the main means to obtain the technical specifications of high-power microwave systems. However, due to the high peak power, short pulse time, and complex measurement environment of high-power microwave radiation fields, accurate measurement of radiation field power has always been a technical problem. The basic idea of ​​the current high-power microwave rad...
