提出了一种使用微波检查三维均匀介电散射体的混合方法。即，所考虑的方法包括两个步骤：首先，通过线性采样方法检索散射体的支撑；然后通过蚁群优化算法估计目标的介电常数。所描述的策略结合了线性采样方法的效率和随机过程的全局优化能力。数值结果评估了该方法在存在噪声的情况下的能力。
A hybrid approach is proposed to inspect three-dimensional homogeneous dielectric scatterers by using microwaves. Namely, the considered method consists in two steps: first, the supports of the scatterers are retrieved by the linear sampling method; then the permittivities of the targets are estimated by an ant colony optimization algorithm. The described strategy combines the efficiency of the linear sampling method with the global optimization capabilities of the stochastic procedure. Numerical results assess the capabilities of the approach also in the presence of noise.
