A real-time plotting method based on mass data layering

Abstract

The invention proposes a real-time plotting method based on mass data layering, which belongs to the field of radar data processing and application. Firstly, the present invention establishes corresponding database tables for different map levels, calculates the unit longitude and latitude range corresponding to the next pixel of each map level, and counts the number of targets in each unit longitude and latitude range under the current level; then, divides the map into Unit rectangular areas of the same size, and number each area under different map levels, calculate the latitude and longitude range of each map unit area under different levels; finally, query the corresponding library table according to the current map level and the latitude and longitude range of the visible area, Add and delete data through the data cache array, and traverse the array for plotting. This method realizes the real-time plotting of massive data, improves the speed of data query, the accuracy and smoothness of plotting, and provides a basis for analyzing the law of target activities and radar detection efficiency.

Description

technical field [0001] The invention belongs to the radar data processing and application field in the basic frontier technical field. Background technique [0002] With the widespread deployment and application of radar, the data of radar experiments has been accumulating and increasing. How to effectively analyze these data is the key to discovering the law of target activities, verifying the core technology of radar, and further improving and improving radar performance. Plotting the target trajectory points on the map is the most intuitive and effective method for analyzing radar test data, but the traditional plotting method is slow in data query and statistics when faced with real-time dynamic plotting of massive points (more than one million levels) , the amount of data is large, and it is prone to the phenomenon that the software freezes for a long time and does not respond, and the software crashes. On the other hand, when the traditional plotting method is used to...
