Abstract

The invention discloses a ship depth fusion positioning method based on radar and Beidou data, which constructs a ship depth fusion positioning model by using ship information acquired by a shore-based radar and ship information provided by a Beidou shipborne terminal, and can realize accurate and reliable positioning of a ship target in a complex water area environment. The method mainly comprises the following steps: firstly, carrying out space-time conversion and unification on radar and Beidou data; then constructing the ship depth fusion positioning model; and finally, carrying out recursive calculation of robust filtering, and obtaining an accurate estimation value of the ship position in real time. According to the method, the position coordinates of the ship can be accurately estimated under the condition that the statistical characteristics of the signal noise cannot be accurately known, and the method has the characteristics of high precision, high reliability, wide applicability and the like.

Description

technical field [0001] The invention relates to the field of multi-source information fusion, in particular to a ship deep fusion positioning method based on radar and Beidou data. Background technique [0002] In order to ensure the safety of ship navigation and improve shipping efficiency, Vessel Traffic Services (VTS) has been widely used in my country's water traffic management departments. VTS uses multi-source information fusion technology to perform fusion positioning of radar target information and AIS target information (Automatic Identification System, automatic identification system for ships), so as to obtain accurate and reliable ship position information. [0003] The traditional fusion positioning method generally sets the signal noise as Gaussian white noise, but in the complex water environment, the uncertain nonlinear noise will change the statistical characteristics of the noise of the sensor, making the noise model preset by the traditional method inconsi...
