Quadratic Correlation Time Delay Estimation Algorithm Based on Kaiser Window and Hilbert Transform


There is a tiny difference between the main peak and side peaks after the traditional quadratic correlation calculation in the time-delay estimation of passive acoustic positioning system. It is easy to lead to a wrong peak value when the system resolution is low or mutations caused by noises occur near the side peaks. In order to weaken the influence of… (More)
