Function:

This behavior computes a pHelmIvP depth objective function for optimizing communication performance, similar to BHV_OptAcousDepth, but using a suite of different performance metrics representing coherence properties of the acoustic environment. Metrics implemented include SNR for multipath arrivals with a limited number of boundary bounces, and a metric penalizing multipath fading. In addition to depth dependent ambient noise, this b behavior also allows for including vertical directionality of the noise by including the elevation dependent array gain in the optimization.
