Abstract: An echo profile in a pulse-echo ranging system is processed by determining the relative slope at points on the profile, determining the relative area of each region of positive slope on the profile, identifying within the region having the largest relative area a point of greatest relative slope as a leading edge reference point, and using either said leading edge reference point or a peak within the echo profile as an echo timing measurement point.
Abstract translation: 通过确定轮廓上的点处的相对斜率来确定脉冲回波测距系统中的回波曲线，确定轮廓上的正斜率的每个区域的相对面积，在具有最大相对面积的区域中识别最大点 相对斜率作为前沿参考点，并且使用所述前沿参考点或回波曲线内的峰值作为回波定时测量点。

Abstract: Error correction in an echo pulse is performed by periodically (for example, every 100th pulse) generating a parabola derived from a selected part of the pulse leading edge. An error value is generated from the distance from a leading edge reference point to the peak of the generated parabola or to the echo peak, whichever is less. In this way an error correction is dynamically re-learned.
Abstract translation: 回波脉冲中的误差校正是通过周期性地（例如，每100次脉冲）来产生从脉冲前沿的选定部分导出的抛物线。 从前沿参考点到生成的抛物线或回波峰的峰值（以较小者为准）产生误差值。 以这种方式，动态重新学习纠错。

Abstract: A method for processing echoes in a time-of-flight ranging system or level measurement system. The method comprises a recursive descent parser which is applied to an echo profile to process and identify potential echoes. In another aspect, the method provides for processing the ring down portion of the echo profile.
