Problems solved by technology

[0004] Although there are also studies on echo drawing methods in the field of traditional radar research, due to the relatively low rotational speed of traditional radars, generally below 20 rpm, while the rotational speed of airport surface surveillance radars is as high as 60 rpm, the amount of echo data Large, the traditional echo drawing method is often difficult to meet the display requirements of the airport scene surveillance radar

Abstract

Aiming to solve the difficult problem that real-time echo is hard to be rendered in real time by a conventional scene surveillance radar for a civil airport, the invention provides a rendering method for real-time echo of a scene surveillance radar. The method comprises the following steps: initialization is performed on a rendering display device and a PCI-E capture card; the rendering display device waits for signal input and subsequent processing is performed according to signal types; echo signals are rendered; regions requiring for echo rendering are adjusted; after-glow blanking processing is performed; screen flip processing is performed; and the processing is ended. The rendering method provided by the invention has the positive technical effects that the method can meet the requirements of high rotational speed of the radar for scene monitoring in an airport, achieves real-time rendering to the picture of radar echo and after-glow blanking effect, ensures smooth and flowing display pictures, and is independent of the support of a specific display card.

Description

technical field [0001] The invention belongs to the technical field of radar terminal display, in particular to a method for drawing real-time echoes of a surface monitoring radar. Background technique [0002] With the progress of traffic and the development of economy, more and more flights are taking off and landing at airports, and the runways of airports are getting busier. The research and application of airport surface surveillance radar has gradually become a hot spot for airport runway safety issues. In this field, the terminal display system of the airport surface surveillance radar, as the main communication interface between the entire radar and the user, undertakes the important responsibility of displaying the radar detection results to the end user, and the radar echo is all the information that needs to be displayed to the end user. The most important type of information. Therefore, real-time echo mapping technology is a very important link in the research f...
