The Design And Implementation Of Radar Control And Display Terminal

Making the radar data processing result visually is an important research subject and the display control terminal plays an important part of radar data processing system, and responsible for the visual display of the target point tracing and tracking information after processing for the observer to observe, receiving intervention commands from operator, changing algorithm parameters of data processing system dynamically, adjusting the display of radar range and scanning speed, providing towing and zoom function, display control terminal is interactive interface of the operator with radar data processing system.With the rapid development of multicore CPU, parallel and concurrent programming technology, high-performance graphics and of high speed memory, it is especially important to enhance the system reliability and flexibility, software-oriented display control terminal can reinforce the compatibility and portability of the whole system.At first, this paper made a comprehensive analysis of the function of the display control terminal to the radar data processing system, under the premise of comparing various options, taking platform features and portability into account, fully considered the humanized design of radar display control terminal, combined the main performance and functions index of the control terminal, designing of high reliability and transplantable interface architecture and interface library development.This paper detailed introduced the fundamental principles in Qt to draw the user defined widget, the internal implementation of the underlying characteristics, and explained technology and data flow control used in the entire development process in detail. And ultimately tested on Windows and Linux platform, based on data provided by the laboratory radar data processing system, the display control terminal showed good stability, reliability and great practical prospects and engineering value, what's more, it took full consideration of the humanized design, which had a friendly and beautiful interface.
