Windows 平台上实现射频仿真系统的实时界面演示

Demonstration of Radio FrequencySimulating System on Computer

描述了在Ｗｉｎｄｏｗｓ平台上实现射频仿真系统（ＲＦＳＳ）的界面演示方案，通过自行设计的１２位Ａ／Ｄ转换卡，对反映导引头偏转角大小的电压幅值进行Ａ／Ｄ转换，利用Ｗｉｎｄｏｗｓ提供的定时器，定时采集转换数据，更新界面。综合使用了位块传输动画法和实时动画法，较好地实现了界面演示的实时性和动画效果。

Describes a demonstrating method for radio frequency simulating system on computer with Windows operator system. With the 12 bit A/D converting card, it could convert the voltage to digit in which amplification reflect the deflect angle of guide. With timer provided by Windows, it could sample the converted data and renew the display on screen. By using the animation method of piece map transmission and timer, the domonstration in time and the effect in animation have been achieved.
