Backscatter Literature Survey


Book Description

A survey of the literature pertaining to backscatter is presented in bibliographical form. Authors' abstracts have been included whenever they were available and appeared adequate. The survey is intended to cover the period from the inception of the study of ionospheric backscatter (about 1928) through 1960. This survey deals mainly with ionospherically propagated backscatter at HF. Some work on terrain returnAND ON DIRECT BACKSCATTER FROM DISCRETE OBJECTS IS PRESENTED, AND THE MAJOR EARLY PAPERS ON INCOHERENT (exospheric) scatter from electrons have been included. Material dealing with troposcatter, ionoscatter, forward propagation at HF, and meteoric and auroral echoes has, in general, been excluded. (Author).







Preliminary Report on Flight Tests of an Airplane Having Exhaust-heated Wings


Book Description

Flights have been made with an airplane in icing conditions in order to test the effect of exhaust heat applied to the wings as a means of preventing ice formations. Other ice-prevention equipment, including an exhaust gas-heated pitot-static head, hot-air-heated windshield, and an inflatable de-icer of recent design, were also tested.




General Relativity and Gravitation


Book Description

The Tenth International Conference on General Relativity and Gravitation (GR10) was held from July 3 to July 8, 1983, in Padova, Italy. These Conferences take place every three years, under the auspices of the International Society on General Relativity and Gravitation, with the purpose of assessing the current research in the field, critically discussing the prog ress made and disclosing the points of paramount im portance which deserve further investigations. The Conference was attended by about 750 scientists active in the various subfields in which the current research on gravitation and general relativity is ar ticulated, and more than 450 communications were sub mitted. In order to fully exploit this great occur rence of experience and creative capacity, and to pro mote individual contributions to the collective know ledge, the Conference was given a structure of work shops on the most active topics and of general sessions in which the Conference was addressed by invited speakers on general reviews or recent major advance ments of the field. The individual communications were collected in a two-volume publication made available to the participants upon their arrival and widely distributed to Scientific Institutions and Research Centres.
