6-18GHz multi-channel front-end receive and transmitting system

Abstract

The invention discloses a 6-18GHz multi-channel front-end receive and transmit system. The system includes a receiving and transmitting part, a front part, an azimuth measuring part, a frequency measuring part, a transmitting source part, a self-detecting source part and a shielding box. Firstly, outer frequency signals in the range of 6-18GHz are received to the receiving and transmitting part through four antennas. And then the four signals are filtered, clipped, amplified and power distributed through the front part, some of them enter the azimuth measurement part, and the azimuth information is extracted after signal processing. The other part of the signal enters the frequency measurement part and extracts the frequency information after signal processing. Finally, the transmitting source part generates the signal with the same characteristics, and transmits the signal through the receiving and transmitting part to achieve the interference effect. The self-test source section provides a self-test signal to check that the main channel is functioning properly. The invention has the advantages of high integration, wide working frequency band and high index consistency, and has wide application prospect.

Description

technical field [0001] The invention belongs to the field of microwave technology, in particular to a 6-18GHz multi-channel front-end receiving and transmitting system. Background technique [0002] With the rapid development of radar communication, electronic reconnaissance and electronic countermeasures and other fields, the signal processing capability of microwave radio frequency signals in complex environments is getting higher and higher. Among them, the receiving and transmitting system is an electronic integrated system widely used in electronic reconnaissance and electronic countermeasures. It can quickly search for the azimuth and frequency information of external signals during electronic reconnaissance; external signal, and quickly emit an interfering signal with the same characteristics. [0003] The traditional receiving and transmitting system is usually assembled by several components, and each component needs to be debugged independently. The main disadvant...

AI Technical Summary

Problems solved by technology

[0003] The traditional receiving and transmitting system is usually assembled by several components, and each component needs to be independently debugged. The main disadvantages are: 1) the working frequency band is narrow, and the channel consistency is poor; 2) the integration is low, the volume is large, and the cost is high; 3) The amount of debugging is large, and it is prone to failure

Therefore, it cannot meet the needs of a wide-band multi-channel front-end receiving and transmitting system with high integration and high performance indicators
