Abstract

The invention provides a three-dimensional displaying method for synthetic aperture radar imaging data. The method includes: step A conducting noise reduction and interpolation on received original three-dimensional synthetic aperture radar data M0 (x, y, z, v) to obtain three-dimensional synthetic aperture radar data including target three-dimensional space coordinate information (x, y, z) and back scattering information v; step B conducting three-dimensional curve reconstruction on the three-dimensional synthetic aperture radar data subjected to noise reduction and interpolation to obtain three-dimensional grid data; step C utilizing a three-dimensional graph drawing assembly line to draw the three-dimensional grid data to obtain a three-dimensional graph to achieve three-dimensional displaying of the three-dimensional synthetic aperture radar data. According to the method, the three-dimensional graph drawing assembly line is utilized to draw the three-dimensional grid data to obtain the three-dimensional graph to achieve the three-dimensional displaying of the three-dimensional synthetic aperture radar data.

Description

technical field

[0001] The invention relates to the field of radar technology, in particular to a method for three-dimensional display of synthetic aperture radar imaging data. Background technique

[0002] With the development of computer technology, 3D visualization technology has been applied more and more. Mature technologies for rendering three-dimensional data include OpenGL graphics API and D3D graphics API. OpenGL is a software interface for graphics hardware. It can use the functions provided by it to construct a scene model, and it is easy to implement coordinate transformation, coloring, lighting, texture mapping, etc. on the model to enhance the authenticity of the scene. In versions above OpenGL3.0, support for shaders is also added. Developers can program the fixed functions of OpenGL, making it easier for 3D scenes to meet the requirements of authenticity. The OpenGL graphics API can run across platforms, while the D3D graphics API can only be supported by t...
