快速迭代反卷积算法的超分辨性能分析

传统观念认为，扫描体制下的实孔径雷达方位分辨力决定于3dB波束宽度，这使得雷达难以从方位上区分同一波束内的两个等距目标。迭代反卷积算法是一种简单实用的超分辨算法，为分析迭代反卷积算法的超分辨性能，文章对线性迭代算法和P阶决速迭代算法进行了比较并对此做了仿真实验。仿真实验表明，P阶快速迭代反卷积算法的超分辨效果较佳，而且...

Analysis on the Super-Resolution of Fast Iterative Deconvolution Algorithm

Traditionally, angular resolution of the real aperture radar based on scanning system is determined by the 3dB beam width, which makes it difficult to distinguish between two goals within the same radar beam whose distances are same. Iterative deconvolution algorithm is a simple and applied super-resolution algorithm For the analysis on the super-resolution performance of iterative algorithm, linear iterative algorithm and p-order fast iterative algorithms were compared in this paper, and simulation experiments were made. Simulation results show that, p-order fast iterative deconvolution algorithms had better performance of super-resolution, and needed fewer numbers of iteration.
