Problems solved by technology

[0008] 1. When the display scale of the electronic chart changes, the related technologies generally use radar images of fixed scales converted from recorded radar data, so it is difficult to superimpose on electronic charts of different scales, even if it can There will also be large deviations in superposition
[0009] 2. Under the same display scale, due to the difference in the coordinate system and display algorithm between the electronic chart (Mercator) and the radar data (polar coordinates), the existing radar image superimposed on the electronic chart still has different coordinate systems and Errors caused by different display algorithms, even for different radar image sources displayed in the

Abstract

The invention provides a radar image simulation system and method based on an electronic chart and navigation data. The radar image simulation system comprises a navigation data receiving unit for receiving and processing real-time navigation data of a ship, an extracting unit for extracting electronic chart vector information from the electronic chart in a corresponding range according to the real-time navigation data, a radar analog image generating unit for generating radar analog images according to the electronic chart vector information and the real-time navigation data, a radar analog image stacking unit for stacking the radar analog images on the electronic chart in the corresponding range, and a display unit for displaying the stacked electronic chart. According to the invention, the radar images of the real-time dynamic ship are stacked, no radar data needs to be acquired, and the radar images can be generated without a complex coordinate transformation algorithm, so that the product cost is reduced while the offset of the stack of the radar images of the electronic chart and the storage space of a computer are reduced.

Description

technical field [0001] The invention relates to the technical field of ship navigation, in particular to a radar image simulation system based on electronic charts and navigation data and a radar image simulation method based on electronic charts and navigation data. Background technique [0002] As an important component of a ship's integrated navigation system, electronic charts and navigation radars are systems that display maritime safety information for mariners when a ship is sailing, and play an extremely important role in ship navigation and collision avoidance safety. However, the use of both alone has certain limitations. With the application and development of modern navigation information technology, in order to better improve the safety of maritime navigation, it has become possible and inevitable to realize the overlay display of radar images and electronic charts. Overlaying and displaying the radar image on the electronic chart can provide the positional rel...
