摘要 该文提出了一种基于遗传算法的雷达目标一维散射中心提取方法并给出了适用条件。它采用非衰减指数和 模型与CLEAN方法,将每个散射中心的提取转化为一个非线性优化问题,并利用遗传算法进行优化求解。仿真结 果表明,相对于传统的FFT方法和Prony方法,该文提出的一维散射中心估计方法在准确性、鲁棒性和分辨力等 方面具有优势。 A novel 1-D scattering center extraction method based on genetic algorithm and its applicable conditions are provided in this paper. The undamped exponential model and CLEAN method are used in the extraction algorithm to transform 1-D scattering center extraction into non-linear optimization problem with genetic algorithm. Experimental results show that the proposed extraction method has advantages in accuracy, robustness and range resolution, comparing with the FFT and Prony methods.
