文中为了实现在信号接收系统中接收信号强弱自动控制的需求，提出了一种自动增益控制（AGC）的设计方案，并且以两级放大器AD603为核心控制芯片，设计了一种应用于相位法激光测距的自动增益控制电路。经过实践证明，这种方法有效地解决了因测量距离的远近不同而导致回波信号幅度变化大的问题，从而减小了后续电路的处理难度，达到了设计要求。

In order to achieve the automatic control requirements of the signal strength in the received signal receiving system , the paper proposed an automatic gain control (AGC) design,which is with two amplifier AD603 as the core control chip,it designs an automatic gain control circuit used in phase method for laser ranging.Practice has proved that this method effectively solved the problem of echo signal amplitude variations that caused by different measuring distances ,thus reduce the difficulty of subsequent processing circuitry and achieve the design requirement.
