A method for processing an echo amplitude profile generated by a pulse-echo ranging system

摘要

The echo amplitude profile is considered as a result of convoluting a single echo with a channel response sequence. For multiple echo detection, the estimation task is broken into the following three major steps:- estimating the channel response,- recovering the full shape of a single echo, and- iteratively update the channel response and echo shape for accuracy.;The estimation of the channel response is treated as a single echo detection problem and includes the steps of:- estimating the strongest echo for its position and amplitude,- removing the echo corresponding to this recovered channel from the echo amplitude profile, and- repeating the preceding steps for the next strongest echo.
