Microwave darkroom array simulation control method and system

Abstract

The invention discloses a microwave darkroom array simulation control method and system. The microwave darkroom array simulation control method includes: calibrating connected lower computer equipmentaccording to a pre-configured instrument alignment calibration table, wherein the lower computer equipment includes one or more of the following parts: a signal source, a vector network, a array plane and a turntable; arranging a microwave darkroom array according to an azimuth elevation angle of a to-be-simulated target, and detecting triplet information values which are of the target and correspond to three antenna branches in the microwave darkroom array; determining phase shift values and attenuation values corresponding to the triplet information values, and generating, on the basis of the phase shift values and the attenuation values, a phase shift control code and an attenuation control code corresponding to the microwave darkroom array at each frequency point. Therefore, the lowercomputer equipment of the microwave darkroom array is automatically calibrated, a microwave darkroom array simulation control process is modularized, thus portability and real-time performance are improved, and the method has extremely high applicability, and can apply to different microwave darkroom environments.

Description

Technical field [0001] The invention belongs to the field of communication technology, and in particular relates to a simulation control method and system for a microwave anechoic chamber array. Background technique [0002] With the rapid development of communication theory and technology, array antennas are playing an increasingly important role in mobile communications, broadcasting stations, radars and other radio systems. The processing performance of array signals directly affects the performance of the entire communication system. . Microwave anechoic chamber, also known as radio wave non-reflective chamber or absorbing chamber. Microwave anechoic chambers provide a relatively quiet electromagnetic measurement environment that can suppress internal electromagnetic multipath reflection interference and shield external electromagnetic interference by absorbing as much incoming waves as possible. [0003] The microwave anechoic chamber array is used in electromagnetic environ...

AI Technical Summary

Problems solved by technology

[0004] At present, the industry is vigorously developing the microwave anechoic chamber simulation technology, but they are generally committed to the solution of the microwave anechoic chamber, but there is no good solution for its control software, which makes it difficult for the control software to be transplanted between different microwave anechoic chamber environments. lead to long development cycle
