基于高尺度分形差量的海杂波背景下小目标检测
Small Target Detection in Sea Clutter Based on Difference of High Scale Multifractal
摘要
Abstract
To reduce the strongly dependencein of sea condition in the detection of the small target in the background of sea clutter and improve the accuracy of the detection,in this paper,the difference of high scale multifractal is applied to propose a new method of small target detection in sea clutter.At first,multifractal detrended fluctuation analysis method (MF-DFA) is adopted to analyze the multifractal property of IPIX sea clutter.The multifractal parameter H(q) is estimated to solve the detection of small target from sea clutter in different sea conditions in this paper.Then,determination method of the difference of high scale multifractal △H(q) is given and influence of the different q on △H(q) is also discussed.Results show that multifractal property of IPIX sea clutter is affected by sea conditions and radar polarizations.When there is small target in IPIX sea clutter on high scale,the relationships of multifractal parameter H(q) and scale q can be similar to a tangent function.When select appropriate scate q of multifractal parameter,the difference between sea clutter and small tarfet can be enlarge.Compared with fluctuation analysis method,the difference of high scale multifractalimproves the detection threshold of small target detection in IPIX sea cutter.关键词
