Sonar-based navigation systems have been immensely used for over a century. Underwater navigation is primarily achieved using Sonar, as Laser-based systems are largely ineffective due to the darkness of the oceans. However, the use of Sonar waves for navigation other than underwater has been very limited. The rise in demands of autonomous systems like self-driving cars and unmanned aerial vehicles have posed new challenges in designing sensor systems. Sonar-based sensors, with the unique properties of sound waves, present themselves as a possible solution, especially in scenarios where visibility is heavily compromised by smoke, dust or other suspended particles. The motivation for using Sonar arises from the flight pattern of bats. Bats are able to effectively navigate in dense vegetation using echolocation and are able to map surroundings for which other animals rely on their vision. In this thesis, we present the design of a data acquisition system with the ability to simulate bat echolocation by generating sonar-waves and recording the resulting echoes. The first part of the thesis focuses on the hardware circuit design for the ultrasonic peripherals. A software interface for the hardware circuit is developed which allows control and flexibility over the hardware not possible on existing sonar-based solutions in the market. To evaluate the practicality of the sonar-based sensor, we design an experimental setup to quantify its performance using resultant echoes, in conditions where visibility is compromised. An artificially generated fog and a LIDAR-based sensor are used to simulate the environment. Experiments are carried out to determine the effect of distance and fog density on the sensor’s performance. The simulated environment and the sonar-board are also used to determine the response of different frequencies in the sonar spectrum. We conclude that the sonar-based board can be effectively used in environments with very high levels of fog to detect objects.
