The standard reflective multipath analysis is summarized briefly, and developed to include other effects, often neglected in text-book analyses, such as curved earth, spatially-extended targets, and frequency agility. In the main part of the paper we show that refractive multipath also exists, given certain atmospheric temperature profiles which may occur quite frequently. The circumstances that give rise to such anomalous multipath are discussed, and the pattern factors are calculated. These are quite different from the pattern factors expected for standard reflective multipath.
