【摘要】 提出了一种基于 Mallat 算法快速检测目标发生机动的方法。该方法利用小波变换获取多分辨率测量数据,计算简单,机动检测延迟小,有效增加了机动检测概率。本文运用该方法对目标运动轨迹进行5层小波分解,仿真表明能将目标的机动从强噪声中提取出来,清晰地看到机动发生的时刻,提高了跟踪效果。更多还原

【Abstract】 A kind of quickly maneuvering detection method based on Mallat algorithm was proposed.The wavelet transform is employed to obtain the multi-resolutional measurement data with the advantages of simple calculation and short delay-time.Thus the probability of maneuvering detection is increased efficiently.Wavelet transform is utilized at five resolution levels to the target track based on the algorithm.The simulation indicates that the target maneuvering can be extracted from strong-noisy circumstance,the maneuvering can be displayed clearly,and the approach can be improved for target tracking.更多还原
