Abstract

The invention discloses a river cross section two-dimensional display system. The system comprises an A / D collection module, an FPGA processing module, and a liquid crystal display, wherein radar data is collected through the A / D collection module and transmitted to the FPGA processing module, the collected data is filtered through the FPGA processing module, clutter in a radar signal collected by a unit module is filtered, and calculation is carried out according to a hydrodynamic formula through a hydrodynamic decoding speed unit module, the speed of water flow is decoded, and a river cross section structure is analogous to a grayscale image, so that pseudo-color transform can be carried out; a cyclic encoding unit module performs cyclic encoding on water flow speed distribution, so that the encoded data can be gradually scanned on the liquid crystal display through three primary colors RBG for displaying a speed image of a river. According to the technical scheme, a river cross section data analysis result is more vivid and intuitive, and the mastery of a topographic change situation is very important for hydrologic observation, search of a suitable navigation channel and research on hydrologic characteristics of the river.

Description

technical field [0001] The invention relates to the technical field of river monitoring, in particular to a two-dimensional display system for river sections, including an A / D acquisition module, an FPGA processing module, and a liquid crystal display. Background technique [0002] The method of radar remote sensing non-contact measurement has good mobility, flexibility and real-time performance, and can be used for hydrological surface information measurement under complex geological conditions and external harsh weather conditions. This method ensures the reliability of measured data. Secondly, in the process of plane two-dimensional numerical simulation, the application of visualization technology can better process the calculation data, realize the visualization of data, make the analysis results more vivid and intuitive, understand the cross-section of the river, and grasp the terrain changes to carry out hydrological observation and find suitable Waterways are very imp...
