—、前言 机载平视显示武器瞄准系统,简称HUDWAC,是国外六十年代以来,迅速发展起来的一种新型火控系统。目前,该项技术在我国尚属一项空白。 数字式符号发生器,是国内研制平视显示系统的一项技术关键。在我所研制平视显示系统的过程中,我们科题组对符号发生器,做了一些初步的研究与探讨,并于前几年先后研制出了符号发生器地面原理样机及空中试飞原理样机。空中试飞原理样机,采用国产中规模TTL集成电路,缩小了体积重量,降低了功耗,增加了可靠性。本样机具有七种状态的显示功能,书写符号比较美观,显示画面比较清晰稳定,基本上满足了平视显示系统的使用要求。 二、技术状态 一、显示功能 1、能显示如下七种状态画面 1）示迹线快速射击状态 2）前置跟踪攻击状态 3）空对空导弹攻击状态 4）导航状态 5）系统动态功能检测状态 6）静态精度检测状态 7）静态功能检测状态 -, Preface Airborne head-up weapon targeting system, referred to as HUDWAC, is a new type of fire control system developed rapidly abroad since the 1960s. At present, this technology is still a blank in our country. Digital symbol generator, is the development of head-up display system, a technology key. In the process of developing the head-up display system, our subject group did some preliminary research and discussion on the symbol generator. In the last few years, we have developed the ground prototype of the symbol generator and the prototype of the air test principle. Flight test prototype prototype, the use of domestic scale TTL integrated circuits, reducing the volume and weight, reducing power consumption and increase reliability. The prototype has seven states of display, writing symbol is more beautiful, the display is relatively clear and stable, basically to meet the use of head-up display system requirements. Second, the technical status of a display function 1, can display the following seven status screen 1) shows the rapid firing state of the track 2) tracking the state of the front 3) air-to-air missile attack status 4) navigation state 5) dynamic system function detection State 6) static precision detection status 7) static function detection status
