Problems solved by technology

Therefore, the current frequency resources in the high frequency band can no longer support more single-station radars to join ocean monitoring, which has become one of the most important social factors restricting the promotion and application of ground wave radars

Embodiment 1

[0044] Embodiment 1. The present invention provides a buoy-type high-frequency ground wave radar system, such as figure 1 As shown, the system includes a buoy platform, a sky-wave transmitting subsystem, a ground-wave radar subsystem, and an attitude measurement subsystem; the system is used for inversion of sea wind, wave and current by ground-wave radar.

[0045] The buoy platform is the sea carrier of the ground wave radar, and its structure does not need to be limited, as long as it can be used as the carrier of the ground wave radar deployed at sea.

[0046] The sky-wave transmitting subsystem is set on the shore base to emit high-frequency electromagnetic waves. The high-frequency electromagnetic waves are refracted by the ionosphere to the sea surface, reflected by the sea surface, and received by the ground-wave radar subsystem as sky-wave signals.

[0047] The attitude measurement subsystem measures and obtains the attitude data of the buoy platform in real time.

Abstract

The invention discloses a buoy-type high-frequency ground wave radar system. A buoy platform is used as an offshore carrier of a ground wave radar. A sky wave emission subsystem is arranged on a shore base and emits a high-frequency electromagnet wave. After the high-frequency electromagnet wave is refracted by an ionized layer and is reflected by a sea surface, a sky wave signal is formed. An attitude measurement subsystem measures and acquires attitude data of the buoy platform in real time. A ground wave radar subsystem adopts the ground wave radar to receive a ground wave signal, processes the signal to form a ground wave doppler spectrum. Simultaneously, the sky wave signal is received, ionized layer disturbance compensation is performed on the sky wave signal in a frequency domain and then the sky wave signal is processed to form a sky wave doppler spectrum. The ground wave radar subsystem reconstructs an actual geographic coordinate system according to the attitude data measured by the attitude measurement subsystem and then the ground wave or the sky wave doppler spectrum is used to inverse wind wave flow data in the reconstructed actual geographic coordinate system. The sky wave emission subsystem and the ground wave radar subsystem carry out time synchronization through a GPS synchronization networking mode. The system can detect a sea area with any distance and is suitable for high sea detection.

Description

technical field [0001] The invention belongs to the technical field of marine environment monitoring. Background technique [0002] The economic relationship between human beings and the ocean is developing continuously along the order of "point-line-surface-body", and this development has a tendency to accelerate. The ocean is becoming more and more important, and the influence of the ocean on human beings is also increasing, from the level of human survival to the economic level, and even rise to the level of politics and international relations. However, human beings' ability to monitor the ocean has always lagged behind human ocean practice activities, and currently basically stays at the level of "points" and "lines", which is far from meeting the requirements of real-time monitoring of the "surface" and "body" of the ocean. need. [0003] Weakness in marine monitoring capabilities is a major problem that will long-term affect my country's development of marine econom...
