Abstract
Based on angle measurement data obtained by a monopulse tracking radar tracking the aircraft target in the short range, the statistical characteristics of the angle measurement data are analyzed. Moreover, the important influences and the proportion of the target glint in the entire measurement errors are evaluated in this paper. THen, a new method to suppress the angle measurement errors is developed based on the wavelet multiresolution analysis and the statistical analysis of the aircraft glint. Meanwhile, the explanation of the effect that glint can be suppressed by wavelet processing is developed in this paper. The results show that the precision of angle measurement can be improved about 30 percent. FInally, it is showed that the wavelet package algorithm can be used as a preprocessor of the Kalman filtering.
