Embodiment Construction

[0017] The ship navigation radar comprehensive display method of the present invention comprises the following steps:

[0018] (1) First use the 3D graphics processing library OpenGL or DirectX to do an initialization process according to the graphics hardware and operating environment, for example, call CreateDevice in DirectX to create a device, and call SetRenderState to set the properties of the rendering device.

[0019] (2) The content of the radar comprehensive display is composed of two parts: layered rendering and layered fusion rendering. The principle of layer division is that "direction stability" is uniformly divided into one layer, such as: north stable layer, bow stable layer; "movement stability" is uniformly divided into one layer, such as: ground stable layer, sea layer; single function The division into layers, for example, echo layer, echo afterglow layer and target layer. The order of layered fusion drawing is arranged according to the priority and displa...

Abstract

The invention discloses a ship-navigation radar integrated display method. The ship-navigation radar integrated display method comprises the following steps that firstly, content displayed by radar is divided into a plurality of display layers and all the display layers are independent of one another; secondly, according to the rotation parameters and the translation parameters, the display layers are drawn to a radar screen in an integrated mode in sequence. According to the ship-navigation radar integrated display method, the content displayed by the radar is respectively distributed to the display layers, each display layer is drawn to the screen according to the rotation parameter and the translation parameter, and all the display layers are independent of one another in updating. Therefore, the drawing efficiency is effectively improved, and an extensible drawing method is provided in the mode of vein increase and decrease.

Description

technical field [0001] The invention relates to radar technology, in particular to a comprehensive display method for ship navigation radar. Background technique [0002] Radar uses radio technology to find targets and determine the position of targets in space. It generally includes three important components: radar wave emission, radar echo signal processing, and radar integrated display. Among them, the radar integrated display part is used to draw radar echoes. Draw echo afterglow, draw various navigation tools and tracking targets or AIS icons, and even charts, so that operators can observe the overall sea and land environment, moving targets and measure various parameters of the current environment. In the early radar integrated display system, the echo data processing, target drawing and other navigation tools were completed by a dedicated graphics processing circuit. Although the hardware processing graphics speed of this radar comprehensive display method is fast, ...
