The Beam Based Method (BBM) is inspired by bat echolocation as a novel ultrasonic sonar. The method is designed for a system consisting of an emitter and two receivers with a directional beam pattern and was previously tested in simulation with ideally designed beam patterns of the receivers. This sonar aims to support autonomous robot navigation and provide a bat inspired biosonar to improve target localisation. In this work, the real measured beam patterns associated with 3D printed bat inspired receivers are imported into the BBM. The biomimetic beam pattern should make it possible for the BBM to efficiently discriminate between orientations, thus being accurate in determining target position. The objective of this work is to investigate how the accuracy of the method depends on the choice of the beam pattern. In particular, the receiver shape with a beam pattern close to that of a bat ear should ensure the most accurate estimations with the BBM. This shape will be included in the final sonar system. |
