本文为激光卫星测距接收机设计提供一个定量的基础,从而利用已知的或测量的系统参数给随机的脉冲响应作定时特性估价。这种分析说明统计特性与光电倍增管打拿极倍增过程无关,以及很可能是非泊松特性。文中分析了固定阈值电路、恒比电路和中心接收机,并且证明这种中心接收机性能为最佳。实验结果与理论值的一致性很好,并且证明了中心定时的优越性。
This article provides a quantitative basis for the design of a laser rangefinder receiver to evaluate the timing characteristics of a random impulse response using known or measured system parameters. This analysis shows that the statistical properties are not related to the dynode dynode doubling process, and most probably are non-Poisson properties. The paper analyzes the fixed threshold circuit, the constant ratio circuit and the center receiver, and proves that this center receiver performance is the best. The experimental results are in good agreement with the theoretical ones and demonstrate the superiority of the central timing.
