Algorithms are presented which have been developed for the WRELADS airborne depth sounder for the detection and location of sea surface and sea bottom reflections within the waveform of 256 consecutive 2-ns samples of received green light energy. The algorithms must be flexible to cater to the wide range of sea conditions encountered operationally in the WRELADS testing program and simple to cater to the computational intensiveness of this portion of the overall WRELADS data processing and yet have quantifiable reliability and accuracy. A concept of pulse confidence (related to SNR) is developed and shown to be related to the probability that a pulse detected as a sea bottom reflection is valid.
