为了提高指挥仪输出诸元的平稳性,提高仪器的计算精度,对来自声纳的输入信号进行平滑处理就是十分必要的了。目前已广泛应用数字机对这种断续、离散的信号进行处理。本文提供的是在机电模拟计算机中处理这种信号的一种方法。首先,把来自声纳的具有一定时间间隔的按阶梯变化的断续信号进行平滑,变成随时间变化的连续信号,然后再把平滑后的连续信号进行微分平滑,求出目标的运动速度。
In order to improve the stability of the output of the command instrument and improve the calculation accuracy of the instrument, it is very necessary to smooth the input signal from the sonar. At present, digital machines are widely used to process such intermittent and discrete signals. This article provides a way to process such signals in electromechanical simulation computers. First, the intermittent signals from the sonar with a certain time interval are smoothed into continuous signals varying with time, and then the smoothed continuous signals are differentially smoothed to obtain the target moving speed.
