【摘要】:海上地形環(huán)境復(fù)雜,對(duì)于微小目標(biāo)識(shí)別系統(tǒng),受到海面雜波影響,目標(biāo)物識(shí)別的分辨率變低。海面雜波一般由船舶運(yùn)行引起的波浪起伏地形變化等因素引起,較易與快速移動(dòng)的微小目標(biāo)物重疊,引起目標(biāo)識(shí)別困難。小波濾波是一種高效的過(guò)濾噪聲算法,對(duì)目標(biāo)檢測(cè)中的海面雜波具有很好的過(guò)濾效果,能夠提高微弱目標(biāo)的檢測(cè)效果。本文研究海上雜波的頻率特性,在此基礎(chǔ)上設(shè)計(jì)基于小波濾波的海面雜波過(guò)濾降噪處理技術(shù),最后給出仿真結(jié)果。
[Abstract]:The sea terrain environment is complex, for the small target recognition system, the resolution of target recognition becomes lower because of the influence of sea surface clutter. It is easy to overlap with the fast moving small object, and it is difficult to recognize the target. Wavelet filter is an efficient noise filtering algorithm, which has a good filtering effect on the sea surface clutter in target detection. In this paper, the frequency characteristics of sea clutter are studied, and the noise reduction technology based on wavelet filtering is designed. Finally, the simulation results are given.
