Rader system with reverse-arch-shaped antenna as main antenna

Abstract

The invention discloses a radar system with a reverse-arch-shaped antenna as a main antenna. The radar system comprises the main radar antenna, a first radio frequency network, a first T / R module, a first frequency mixing module, a first receiver, an antenna control module, an auxiliary antenna, a secondary radio frequency network, a second T / R module, a second frequency mixing module, a second receiver, a driving module, a rotary table and an axis angle encoder. The main radar antenna and the auxiliary antenna are located on the rotary table, and the main radar antenna, the first radio frequency network, the first T / R module, 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 module, 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 the main antenna and the auxiliary antenna, signal receiving of the radar system can be more accurate, the problems of receiving errors and the like caused by errors are reduced, the rotary table is controlled in an encoding mode, the rotating angle of the rotary table is accurate, and the function of more accurate signal receiving is provided.

Description

technical field [0001] The invention discloses a radar system whose main antenna is an anti-bow antenna, and 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.
