A bibliography on the development, design, and operation of side looking airborne radar systems is presented.
A bibliography is presented which gives an annotated listing of the reports and papers produced in the first decade of earth-resource imaging radar study (plus a few earlier works) and summarizes the current state of knowledge as represented by publications. An extensive cross-reference index was provided to facilitate the identification of all entries even in small part pertinent to any discipline or aspect of investigation. Identification is made of the affiliation of the authors at the time of their research and, when available, at the present time (1974). In each case where a particular radar was used at a particular place and time, these items were identified.
