High-frequency over-the-horizon radar station selection auxiliary system and method

Abstract

The invention discloses a high-frequency over-the-horizon radar station selection auxiliary system and a method. The auxiliary system comprises an antenna, a transmit-receive switch, an emitting module, a receiving module, a signal processing and transmitting module and a display and control module. The high-frequency over-the-horizon radar station selection auxiliary system is capable of simulating the working mode of the radar to comprehensively test the environment condition of the site selection of a radar station, and analyzing the influence of the environment factor on the radar operation through the detection of an echo, and finally choosing a proper site location according to a testing result. The high-frequency over-the-horizon radar station selection auxiliary system provided by the invention is light, portable and low in power consumption, and capable of evaluating by simulating the actual working mode of the radar and considering the site electromagnetic environment, so that the station site selection is more scientific and effective, and the success rate of the station selection can be increased.

Description

technical field [0001] The invention belongs to the field of high-frequency over-the-horizon radar, and in particular relates to a station selection auxiliary system and method for high-frequency over-the-horizon radar. Background technique [0002] High-frequency over-the-horizon radar usually works in the 3-30MH high-frequency band. With the help of sky wave or ground wave propagation mode, it can realize the remote sensing of dynamic parameters such as wind, wave, and current on the sea surface in a large range, and the effective detection of targets such as ships and low-altitude aircraft. In the detection of sea surface targets, the cost of high-frequency over-the-horizon radar is much lower than that of spaceborne radar systems; It has the advantages of large range, all-weather, and good real-time performance, so it has been widely used in many coastal countries. [0003] High-frequency over-the-horizon radar stations are generally built along the coast. It is neces...

Problems solved by technology

In addition, the signals in the working frequency band of high-frequency over-the-horizon radar are very crowded, and the surrounding electromagnetic environment must be monitored before the station is built.

However, at present, there are many technologies and researches on monitoring the electromagnetic environment test system of high-frequency over-the-horizon radar at home and abroad. The research on the station selection technology of over-the-horizon radar is still blank. assessment of the electromagnetic environment, but cannot monitor the quality of radar echoes and the spectral characteristics of interference

At present, most station selections rely on field surveys and on-site observations by relevant professional and technical personnel, and use experience evaluation to select sites and build stations. This will consume a lot of manpower and material resources, and what is more serious is that there is no auxiliary equipment for monitoring In the process of building a high-frequency over-the-horizon radar network, there have been many examples of station selection failures, resulting in a lot of waste and loss of manpower, material and financial resources
