Wavelet has good localizing quality at time domain and frequency domain simultaneously and the characteristic of multi - resolution ratio analysis, so it can fulfill all kinds of wave - filtering needs such as low - pass, high - pass, sink wave, random noise denoising. compare with readitional wave - filtering methods, wavelet has incomparable advantage. wavelet has become an effective means of signal analysis and is intituled as math microscope of signal analysis
小波分析由於在時域頻域同時具有良好的局部化性質和多解析度分析的特點，因此不僅能滿足各種去噪要求如低通、高通、陷波、隨機噪音的去除等，而且與傳統的去噪方法相比較，有著無可比擬的優點，成為信號分析的一個強有力的工具，被譽為分析信號的數學顯微鏡。 -
Based on above performances the applications of multi - sensor data fusion in state estimation for maneuvering target is studied systemically. the main work includes : based on the analysis that the extreme value of acceleration presupposed causes influence in the “ current ” statistical model, a modified model is given, which utilizes the functional relationship between maneuvering status and estimation of the neighboring intersample position vector to carry out the self - adaptive of the process noise variance. then combining with the recursive characteristic of kalman filter, an improved self - adaptive filtering algorithm is presented
基於此，本文針對多傳感器數據融合技術在機動目標狀態估計中的應用進行了系統的研究，其主要工作如下: 1 、基於「當前」統計模型中加速度極限值的預先設定對于濾波效果影響的分析，利用目標機動狀況與相鄰采樣時刻間位置估計量變化之間的函數關系實現噪聲方差自適應，進而提出了一種修正的模型，並結合卡爾曼濾波遞推演算法，提出了一種改進的自適應濾波演算法。
