Embodiment Construction

[0037] Combine below figure 1 A further explanation of the Beidou buoy wave measurement method:

[0038] Firstly, to collect the Beidou satellite signal (A1) is to use a satellite signal receiving module of a Beidou receiver on the mooring buoy to receive n (3ri , the frequency f of the carrier signal transmitted by each Beidou satellite i Obtained directly according to the technical documentation of the Beidou satellite, the received carrier frequency variable df of each Beidou satellite ri It is obtained by the formula (1), so that n carrier frequency variables df are obtained ri , i=1,2,3,...n; then the calculation of buoy velocity (A3) is based on the principle of Doppler velocity measurement, calculated by formula (9):

[0039] e i 1 V 1 + e i 2 V 2 + ...

Abstract

The invention discloses a Beidou buoy wave measurement method. According to the method, a Beidou satellite receiver installed on a moored buoy is used for receiving Beidou satellite signals from a plurality of Beidou satellites, carrier frequency variables of the Beidou satellite signals can be measured according to the Doppler principle, motion speed of the buoy is calculated, and the spectrum of ocean waves and ocean wave parameters can be calculated. The technical procedures of the method include the steps of collecting the Beidou satellite signals, extracting the carrier frequency variables of the Beidou satellites, calculating the motion speed of the buoy, calculating the spectrum of ocean waves and outputting the ocean wave parameters. The Beidou buoy wave measurement method is easy, only one Beidou satellite receiver needs to be installed on the moored buoy, equipment is simple, cost is low, the wave measurement accuracy is high, and therefore the method has quite wide application prospect.

Description

technical field [0001] The invention relates to a technical method for using a Beidou receiver on a mooring buoy to use the Beidou satellite navigation system to measure ocean waves. Background technique [0002] The wave measuring buoy is one of the most commonly used wave observation instruments at present. It can obtain wave information such as wave height, cycle and wave direction by measuring the motion state of the buoy body on site. It is not limited by water depth and some environmental factors, and has been widely used in on-site observation of ocean waves. [0003] There are two main methods of observing waves by using buoys: one is to use the X-band navigation radar on the shore or on the ship to measure the movement of the buoy body in the sea with the waves to obtain wave parameters; The wave sensor measures the movement of the buoy with the waves and automatically records the wave parameters. [0004] The above-mentioned method of observing waves using buoys ...
