Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.

[0024] like figure 1 As shown, a transceiver integrated high-frequency ground wave radar antenna includes a base 70 , a ground grid 10 , a feed box 20 , a transmitting antenna mast 30 , a receiving antenna body 40 and a lightning receptor 50 .

[0025] The above-mentioned ground net 10 is arranged around the base 70, preferably eight plastic-skinned multi-segment wires that are radially arranged around the base 70, and each plastic-skinned multi-segment wire is effectively connected with the base 70 and laid flat on the base. on the ground. As an alternative, the number of plastic-covered multi-segment wires can also be two, four or other numbers, all of which are within the protection scope of the present application.

[0026] The above-mentioned feed box 20 is arranged on the top of the base 70 , and an insulating block ...

Abstract

The invention discloses a receiving / transmitting integrated high-frequency ground wave radar antenna, including a substrate, an earth screen, a feed box, a transmitting antenna pole, a receiving antenna pole and a lightning arrester. The receiving antenna body includes a shell, a monopole spiral antenna, and groups of closed antennas, a plurality of tuning matching boards and a plurality of amplifying circuit boards which are vertical, wherein a waterproof signal connecting plug is arranged on one end of the feed box. After adopting the above structure, a high-frequency ground wave radar transmitting antenna can be integrated with a portable receiving antenna, thus being compact in structure, small in occupied area and more convenient to erect and maintain; locations of a radar station, in particular to a seaside station is much easier, a convenient approach is provided for establishing a mobile radar station, design cost of a radar is also saved, and great promotion effect is provided for wide popularization and application of the high-frequency ground wave radar. In addition, due to the addition of the lightning arrester at the top, the lightning protection performance of the device is greatly improved.

Description

technical field [0001] The invention relates to a transceiver antenna, in particular to a transceiver-integrated high-frequency ground wave radar antenna. Background technique [0002] High-frequency ground wave radars used to detect ocean surface currents, waves, and wind fields often use phased array antennas to scan radar beams in azimuth. In order to increase the detection distance, this kind of radar generally uses a lower operating frequency of a few megahertz to more than a dozen megahertz, and the antenna array length generally reaches hundreds of meters or even several kilometers. The cost of such a large phased array radar antenna is high. It occupies a large area, and it is difficult to find a suitable area to build such a radar station on the seashore, thus limiting the wide application of this radar. Therefore, how to simplify the antenna structure of high-frequency ground wave radar and reduce the antenna scale has always been a technical problem of widespread...
