摘要
由于优良的抗毁特性,短波通信在当今军事通信中起着重要的作用。发射机控制系统是短波通信系统的重要组成部分之一,同时也是关键技术之一。介绍了发射机系统的组成及功能,并就发射增益控制、温度保护控制等描述了发射控制系统的相关设计。结合具体工程项目,详细讨论了发射机增益控制和保护控制的实现方法。试验表明该设计可以做到有效的增益控制,同时也发挥了良好的保护作用。目前该系统在实际应用中发挥了重要作用。
Shortwave communication plays an important role in the military communications today for its good invulnerability, control system of transmitter is one of shortwave radio communications and key tech-nologies. This paper introduces the components and functions of transmitter, and discusses the control de-sign of the gain and temperature protection of the transmitter. Furthermore, it discusses the applied way of gain control and protection control of the transmitter. The test indicates that this design can make the gain control efficient and play an important protection role. This system plays an important role in the practical application.
