Title: BUOY-TYPE HIGH-FREQUENCY GROUND WAVE RADAR SYSTEM
Abstract:
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 disposed 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 receives a ground wave signal by using the ground wave radar, and 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 by means of a GPS synchronization networking mode. The system can detect a sea region having any distance and is applicable to high sea detection.
