We introduce a new post-processing ultrasonic echo identification algorithm for the special case of two overlapping echoes. Compared to dictionary-based deconvolution, the algorithm has a reduced solution space and can reconstruct echoes that have a better fit with the acquired data. We have tested the algorithm using a synthetic test case using two dissimilar echoes and the algorithm was able to reconstruct the constituent echoes with good accuracy.
