In this paper, a novel design of ultrasonic based surveillance system for rescue and military operations has been presented. The developed system consists of electronic module, transmitter, receiver, digital to analogue converter, liquid crystal display (LCD) and power supply. First, the mathematical model has been presented for the object detection system. Then the numerical simulation has been performed using Matlab plate form. The experiments have been conducted using ultrasonic frequencies. The thin cloth, thin curtain, thick curtain, paper and transparent plastic have been considered as a media during experiments. The presented system is highly accurate for object detection behind the obstacle. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE). Source
