Abstract

The invention discloses a multichannel transmission system of millimeter-wave signals. The multichannel transmission system of the millimeter-wave signals comprises a transmitting module, a receiving module, a local oscillator module, a transmitting switch module, and a receiving switch module. The transmitting module is used for being connected with a transmitting end of transmitting antennas, and the transmitting module is used for sending transmitting signals through the transmitting antennas. The receiving module is used for being connected with a receiving end of receiving antennas, and the receiving module is used for receiving the transmitting signals sent by the transmitting module and changing the transmitting signals into intermediate frequency signals. The local oscillator module is connected with the transmitting module and the receiving module, and the local oscillator module is used for providing local oscillator signals for the transmitting module and the receiving module. The transmitting switch module is connected with the transmitting module, and the transmitting switch module is used for controlling the number of transmitting channels of the transmitting signals sent by the transmitting module. The receiving switch module is connected with the receiving module, and the receiving switch module is used for controlling the number of receiving channels of receiving signals received by the receiving module. Signals transmitting numbers and signals receiving numbers are controlled accurately, so transmitting accuracy of signals is guaranteed.

Description

technical field [0001] The present invention relates to signal transmission technology, in particular to a multi-channel transmission system for millimeter wave signals. Background technique [0002] Millimeter wave: Electromagnetic waves with a wavelength of 1 to 10 millimeters are called millimeter waves. They are located in the wavelength range where microwaves and far-infrared waves overlap, so they have the characteristics of both spectra. The theory and technology of millimeter wave are the extension of microwave to high frequency and the development of light wave to low frequency. [0003] Compared with microwaves in lower frequency bands, millimeter waves have a wide range of available spectrum, large information capacity, and easy to achieve narrow beams and high-gain antennas, so they have high resolution, good anti-interference performance, and strong ability to penetrate plasma. It has the advantages of large Doppler frequency shift and high speed measurement se...
