Abstract

The invention discloses an electromagnetic radiation parameter testing system. The system is composed of a receiving subsystem, a parameter testing subsystem, a signal processing and control subsystem and an auxiliary subsystem. The system can realize automatic testing by use of a lifting rotary turntable, a program-controlled attenuator and a microwave switch, and can automatically monitor and store multiple data; a power divider is used for providing multiple testing channels so as to test and monitor multiple radiation parameters in real time; and an amplitude limiter is used for performing key protection on an easily damaged testing element, thereby guaranteeing the safe work of the system. A wave detector is used for testing the pulse power so as to conveniently acquire the electric field waveform of the wideband time domain pulse; uncorrected envelope technology is used for measuring the pulse signal envelope, and the testing system structure is simplified; the automatic testing and storage of multiple dynamic data can be realized in real time, and a mater control computer and a comprehensive data post-processing software platform can realize seamless link. A powerful means is provided for the electromagnetic radiation testing of a complex electromagnetic environment.

Description

technical field [0001] The invention belongs to the field of microwave technology and electromagnetic compatibility, and specifically relates to an electromagnetic radiation parameter testing system Background technique [0002] Electromagnetic compatibility technology is widely used in industry, science and medicine (IMS) research, and its application fields are expanding. Especially in the case of continuous wave, high power, and long-time working microwave sources, the leakage radiation of microwave space will have a fatal impact on the control circuit at this time. According to relevant literature analysis, cable coupling is the main way for space radiation to cause damage to circuit components. In addition, electromagnetic radiation can also cause serious interference to communication systems. Therefore, in order to ensure the effective work of electronic products and communication systems, it is necessary to conduct space electromagnetic radiation interference. test. ...
