Radar system using dipole antenna

Abstract

The invention discloses a radar system using a dipole antenna. The radar system comprises a radar main antenna, a first radio frequency network, a first T / R assembly, a first frequency mixing module, a first receiver, an antenna control module, an auxiliary antenna, a second radio frequency network, a second T / R assembly, a second frequency mixing module, a second receiver, a drive module, a rotating table and an axis-angle encoder. The radar main antenna and the auxiliary antenna are located on the rotating table. The radar main antenna, the first radio frequency network, the first T / R assembly, the first frequency mixing module, the first receiver and the antenna control module are sequentially connected. The auxiliary antenna, the second radio frequency network, the second T / R assembly, the second frequency mixing module, the second receiver and the antenna control module are sequentially connected. According to the radar system, due to the design of combining the main antenna and the auxiliary antenna, signals of the radar system can be received more accurately, the problem of receiving faults caused by errors is reduced, the rotating table is controlled through encoding, the rotating angle of the rotating table is accurate, and the more accurate signal receiving function can be provided.

Description

technical field [0001] The invention discloses a radar system using a dipole antenna, which belongs to the technical field of signal processing. Background technique [0002] There have been amazing developments in antennas and radars in recent decades, but there have been no major breakthroughs in the Basic Academy. At present, the types and forms of antennas emerge in endlessly, the performance requirements are getting higher and higher, and the application fields are constantly expanding. The urgent needs of military equipment and the national economy promote and lead the rapid development of antenna theory and technology. In many fields of modern science and technology, Automatic control technology plays an increasingly important role. The so-called automatic control refers to the use of external equipment and devices to make it, equipment or production process automatically follow the predetermined law without the direct participation of people. In recent decades, the ...

Problems solved by technology

However, the frequency band of ordinary dipole antennas is very narrow. Some new dipole antennas, such as biconical antennas and double dipole antennas, have obvious bandwidth expansion, but their structures are complex and occupy a large space, which is not suitable for wireless communication. terminal miniaturization
