Abstract: Ultrasonic technique is a latest technique for the measurement of burning rate of solid propellant. PCI based ultrasonic flaw detection card installed in a PC is used to initiate the ultrasonic transducer and store the signals of the reflected pulses in computer memory. This paper discusses the two methods: 1) cross correlation and 2) zero crossing to compute the time lapses from the recorded data. The graphical language LabVIEW utilizing dynamic link libraries developed in C++ is used for developing the entire computation procedure. The software has the advantage of displaying the tracking of the signal and plotting the time lapse against time.
