| 摘 要： | 针对低信噪比情况下目前常用的滤波算法不能同时做到精确和高效跟踪机动目标的缺点,提出一种多分辨率滤波方法用于跟踪低信噪比情形下的机动目标.该算法利用离散小波变换和滤波器组将量测信息分解到不同分辨率的层级,由于在低分辨率下量测的误警率较低,所以在低分辨率层级实现对目标机动信息的提取,可以避免机动信息被噪声所淹没,缺失的信息...

| Abstract: | In order to overcome the disadvantage of the common used filtering algorithms that can not achieve the accuracy and effectiveness at the same time in low SNR maneuvering target tracking,a multiresolution method is proposed for low SNR maneuvering target tracking.This method uses discrete wavelet transform and filter bank to decompose the measurement into different resolution layer,because of the low false alarm ratio in low resolution layer,the maneuvering information could be easily extracted in low resolu... |
