Radar system using main antenna as helical antenna

Abstract

The invention discloses a radar system using a main antenna as a helical antenna. The radar system comprises a radar main antenna, a first RF network, a first T / R assembly, a first mixing module, a first receiving machine, an antenna control module, a secondary antenna, a second RF network, a second T / R assembly, a second mixing module, a second receiving machine, a driving module, a rotary table and a shaft angle encoder; the radar main antenna and the secondary antenna are both positioned on the rotary table; the radar main antenna, the first RF network, the first T / R assembly, the first mixing module, the first receiving machine and the antenna control module are connected in a sequence; the secondary antenna, the second RF network, the second T / R assembly, the second mixing module, the second receiving machine and the antenna control module are sequentially connected in a sequence. According to the radar system, the design of the main antenna and the secondary antenna enables accurate signal receiving of the radar system, and therefore, the problems like inaccurate receiving caused by error can be reduced; meanwhile, the rotary table is controlled through a code, so that the rotating angle of the rotary table is accurate, and as a result, the accurate signal receiving function can be realized.

Description

Technical field [0001] The invention discloses a radar system whose main antenna is a helical antenna, which belongs to the technical field of signal processing. Background technique [0002] In recent decades, there have been amazing developments in antennas and radars, but there have been no major breakthroughs in the basic courtyard. At present, the types and shapes of antennas are emerging in endlessly, performance requirements are getting higher and higher, and the application fields continue to expand. The urgent needs of military equipment and 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 additional equipment and devices to make the equipment, equipment or production process automatically follow a predetermined law without direct participation of people.
