Position Determination of an Aircraft Using Acoustics Signal Processing
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 8
Abstract
This paper deals with the determination of an aircraft position using the acoustic source emitted from it. As per the experimental setup, sound energy emitted from the aircraft is captured with the help of microphones and processed further using MATLAB toolbox and LABVIEW software. Localization algorithm is sub divided into two categories, in which the first method involves time delay estimation of acoustic source through simulation process and the second method is analyzing the Doppler frequency shift from the aircraft sound. Using the above methods the navigation parameters such as velocity, Height, Mach number, RPM of the propeller, Elevation angle and slant range will be determined.
