On the solution of ill-posed inverse electromagnetic problems
Abstract
The fundamentals of selected algorithms are outlined, and their use for the solution of linear or locally linearized inverse electromagnetic problems is illustrated. Emphasis is on the attainable spatial resolution and the stability of the solution against approximation, measurement and computational errors. The relevant physical meaning of the various terms in the inversion procedures is discussed, and results on the performance of Kalman filtering in remote sensing indicate that an improvement in stability and in resolution is attainable.
