摘要
针对近程伪码调相毫米波雷达复杂目标回波具有很强非线性的特点,以伪码调相毫米波雷达相关处理后的回波数据为对象,以分形理论为工具来研究目标回波的复杂性和不规则性,提出将目标回波的分形维数作为特征参数。外场实测数据计算结果表明,不同目标的关联维数有较明显的差异,可以作为特征参数用于目标分类和识别。
For pseudo-random code continuous wave(PRC-CW) radar,most investigations have not placed strong emphasis on echo signal feature extraction and recognition.In this paper,the target echo after correlation processing in PRC-CW radar is analyzed utilizing the fractal theory.In this paper,it is suggested to take the fractal dimension of the target echo as its feature.Correlation dimensions of three kinds of moving targets are estimated and compared.It is shown that the correlation dimensions of different targets...
