摘要
选择谐波函数作为散射源的表征基函数,利用随机矩阵进行观测,实现了对散射源的稀疏表征,最后通过正交匹配追踪算法解算出表面散射源.利用压缩感知—正交匹配追踪算法与直接求解矩阵方程所得到的散射远场分布一致.
Harmonic functions are selected as basis, and scattering source is rebuild by orthogonal matching pursuit algorithm （ OMP） , which is observed by random matrix. Scattering far field patterns calculated by CS-OMP and LU decomposition agree well.
