ITERATIVE LEARNING ADAPTIVE SONAR SYSTEM, APPARATUS, METHOD, AND COMPUTER PROGRAM PRODUCT

Abstract:

A learning SONAR system and method including receiving, at an input, mission parameters including one or more of mission accuracy, mission covertness, learning rate, and training matrix dependency; transmitting pulsed signals; receiving return pulsed signals, for instance, using a tunable acoustic receiver having controllable receiver elements; and determining a number of the controllable receiver elements to generate estimates of altitude and 3D velocity based on a combination of transmit power, signal-to-noise ratio, and altitude range using an adaptive spatial sampler of a learning controller.
