Abstract

The invention provides a frequency sweep measurement method and frequency sweep measurement system based on a diversity concept. The frequency sweep measurement method comprises the following steps: an emission frequency receiving at least one frequency sweep signals, and radiating the frequency sweep signals to space; a multi-port detected antenna with two mutually orthogonal receiving ports receiving the frequency sweep signals, and obtaining main polarization signals and cross polarization signal; a receiving device receiving the main polarization signals and the cross polarization signals; and a processing unit obtaining level of the main polarization signals, the level of the cross polarization signals and an rotation angle of the multi-port detected antenna, and generating and outputting an antenna direction map according to the level of the main polarization signals, the level of the cross polarization signals and the rotation angle of the multi-port detected antenna.

Description

technical field [0001] The invention relates to an antenna measurement system, in particular to a frequency sweep measurement method and a frequency sweep measurement system based on the concept of diversity. Background technique [0002] At present, the antenna measurement system usually has two forms. One is composed of a synthetic signal source, a transmitting antenna, an antenna under test, a radio frequency switch, a single-channel joint, and a spectrum analyzer. Its working principle is: the synthetic signal source passes through The transmitting antenna transmits a specific single-frequency sine wave signal into the space. After the antenna under test receives the specific frequency signal transmitted by the transmitting antenna, it is gated by a radio frequency switch and then transmitted to the input terminal of the spectrum analysis through a single-channel joint to realize Continuous and uninterrupted data acquisition of electromagnetic wave signals in 360° direct...
