Monopulse radar angle measurement error reduction based on wavelet multiresolution analysis

Based on the statistical analysis of the monopulse radar angle measurement error in the close distance, the long term dependence and 1/f-type spectrum are shown. Moreover, from the point of view of the long term dependence, the effectiveness of available processing techniques are explained. Since wavelets are particularly well suited to study the strong correlation structure signal, the wavelet multiresolution analysis is employed in analyzing and processing the angle measurement error in this paper. The result shows that the angle measurement error can be properly reduced by the wavelet preprocessor
