The large number of millimetre and microwave terrestrial links that are in operation has lead to the belief that it may be possible to estimate two-dimensional rainfall rate fields. This paper outlines a reconstruction algorithm that can be used to estimate the rainfall field from a number of measurements of path attenuation on terrestrial links. In this paper we adopt a different approach to the regularization of this inverse problem. The main focus of the paper is a description of the retrieval algorithm which is demonstrated through simulation. The approach has been shown to be robust and relatively insensitive to errors and quantisation in the link measurements.
