自雷达设备问世以来,其主要的终端显示单元特别是PPI平面位置显示器一直沿用随机扫描体制的显示器。随着雷达、通讯、,情报网等设备的迅速发展,需要在雷达终端上显示的信息愈来愈多,传统的随机扫描体制显示器已难以胜任。本文介绍新近研制的一种高性能光栅扫描体制的雷达显示器。该显示器集高分辨光栅显示、高分辨率图形图象处理、高速数字信号处理、超大规模门阵列、微计算机和智能化管理软件等高新技术于一体,适用于各种军用雷达、机场雷达和舰船用雷达作为终端显示设备。 显示器画面印象为2048×2048象素,图象灰度或色彩256种,可选颜色4096种,显示窗口为1600×128O象素,可在整个画面印象区内连续漫游。显示器采用嵌入式、模块化的体系结构,具有很好的灵活性和通用性,并且全部采用CAD设计、调试,为今后批量生产提供了有利条件。 本文将对该显示器的基本原理、设备组成和系统软件作较详细的介绍。
Since the advent of radar equipment, its main terminal display unit, especially the PPI flat panel display has been using a random scan system display. With the rapid development of such equipment as radar, communications and intelligence networks, more and more information needs to be displayed on the radar terminal, and the traditional random-scan system display has been difficult to handle. This article introduces a newly developed radar display with high performance raster scanning system. The display combines high-resolution raster display, high-resolution graphic image processing, high-speed digital signal processing, ultra-large-scale gate array, micro-computer and intelligent management software and other high-tech in one, suitable for a variety of military radar, Marine radar as a terminal display device. Display screen image impression of 2048 × 2048 pixels, the image gray or 256 kinds of colors, optional color 4096 kinds, the display window is 1600 × 128O pixels, continuous roaming in the entire image impression area. Display with embedded, modular architecture, with good flexibility and versatility, and all use of CAD design, commissioning, mass production for the future to provide favorable conditions. This article will monitor the basic principles of the device components and system software for more detailed introduction.
