摘要
针对脉冲体制激光近炸引信系统中回波幅值变化大、控制难的不足,采用AD603组成两级动态范围为40dB的应用电路,实现了窄脉宽信号的自动增益控制。结果表明有效地控制了激光回波幅值的变化,提高了定距精度。
In order to solve the problem of significant change of echo signal in the laser proximity fuze system, an application circuit was adopted which was formed by two levels of AD603 and whose dynamic range is 40dB. Thus the narrow pulsed width signal can be controlled with it. The results of test indicate that it can effectively control the change of echo signal of laser proximity fuze, and the precision is enhanced.
