| Abstract: | The adaptive algorithm on the LMS is described. An adaptive algorithm applying cubic smoothing, quadratic interpolation of seven points is then developed. Time delay estimation for helicopter localization is performed using this algorithm. Based on the experimental data of a helicopter's noise in the field, numerical calculation and simulation of the time delay estimation are carried out using a computer. The results of calculation and simulation are found to be satisfactory. |
