Echoic flow for cognitive radar guidance

Abstract

Echoic flow is an inherently cognitive method for linking action and perception in radar and sonar systems. In this paper, we describe a first demonstration using echoic flow to guide a robotic vehicle autonomously around an unknown course. We briefly introduce the key concepts that underpin echoic flow and describe how echoic flow can be used to form a cognitive guidance system. Full-scale experiments with a robot platform demonstrate the advocated technique able to traverse a square corridor course where one of the sides has the extra complication of a chicane feature.
