Abstract

The invention relates to the technical field of radar detection, and in particular relates to a transmitting-receiving shared antenna applied to a high-frequency ground wave radar. The transmitting-receiving shared antenna disclosed by the invention is characterized by comprising a monopole transmitting-receiving shared antenna body, a transmitting-receiving shared antenna switch, a first electrical tuning ring antenna, a control impulse forming circuit, a control voltage forming circuit, a first electrical tuning ring antenna transmitting-receiving control circuit, a second electrical tuning ring antenna and a second electrical tuning ring antenna transmitting-receiving control circuit. By using the transmitting-receiving shared antenna, the problems that because the occupied area of the antenna system of the ground wave radar is large, a radar target is large and easy to damage, an ideal erecting field is not easily found and the like can be solved.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a common antenna for transmitting and receiving applied to high-frequency ground wave radar. Background technique [0002] High-frequency ground wave radar detects ocean state parameters or detects moving targets on the sea surface. There are currently two forms of its transmitting and receiving antennas. One receiving antenna is an array phased array antenna, and the transmitting antenna is a Yagi antenna. The ground area is wide, generally ranging from 300 meters to 1,000 meters, and is vulnerable to damage. The other is a compact antenna that uses a so-called monopole crossed-loop antenna combined with a monopole and two mutually orthogonal loop antennas. The transmitting antenna is also a Yagi antenna. figure 1 is a schematic diagram of a phased array radar receiving antenna in the prior art; figure 2 It is a schematic diagram of monopole cross receiving and transm...
