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.
