Abstract 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.
