Abstract—Now computerization is the most popular, reliable and flexible design for various types of control and communication systems. Sound navigation and ranging (SONAR) is a modern ultrasonic range finding technique used for collecting the information about a distant object without any physical contact. In this research work a PC based active SONAR system is proposed. A pair of 40 kHz piezoelectric ultrasonic transducers is used in this project. A driver-software named is developed using turbo C language aimed at IBM PC and its clone machines. The software provides necessary support for interfacing the hardware as well as calculations. A numbers of test were done and found that the proposed system performances are good in terms of accuracy ±5%, simplicity, cost and power consumption.

Index Terms—SONAR, under water radar, ultrasonic range finder, ultrasound, computer interfacing, piezoelectric transducer.
