Abstract
A new processing technique of sonar echoes is introduced to estimate the inclination angle of a planar reflector. Correlation with normalized echo amplitude model and its derivatives has improved estimation accuracy. Experimental results show how a single transducer placed on a step motor can be used for estimating the reflector´s orientation on a sensor coordinate system.
