Method and system for constructing test electromagnetic signal environment

Abstract

The invention belongs to the technical field of electromagnetic environment tests and discloses a test electromagnetic signal environment construction method and system. According to the method, a measurement sensor of the system is adopted for transmitting acquired electromagnetic environment radiation source parameter information to an element information collection / distribution center through a data transmission line; the element information collection / distribution center is connected with an electromagnetic environment computing / control center through a data line, and the output end of the element information collection / distribution center is connected with an electromagnetic signal synthesis transmission terminal. According to the method and system, a radiation source signal constructing an electromagnetic environment is modeled by adopting a primary element based signal description method, so that the accuracy and completeness of a signal environment model are improved; and an electromagnetic environment evaluation method combining primary element and multi-band real-time evaluation is adopted, so that the unsatisfactory primary element information of a radiation source can be quickly evaluated and located, the working parameters of the radiation source can be quickly adjusted, the electromagnetic environment construction efficiency and repeatability are improved, and the cost-benefit ratio can be increased.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic environment testing, and in particular relates to a method and system for constructing a testing electromagnetic signal environment. This method is especially suitable for the construction and control of the dynamic electromagnetic environment for electronic information equipment testing. Background technique [0002] The elements of the electromagnetic signal environment refer to independent and irrelevant basic signal parameters that describe the signal, which can describe the state and change of the signal and the signal environment, and are controllable in the test. In addition, it also includes descriptive elements for other electromagnetic environment elements, which are used to describe the signal and the influencing factors of the signal environment, such as platform motion and antenna rotation, etc. These elements can also be expressed as a certain type of parameters, such as moti...
