Aerospace Instrument-Making Annotation << Back Detection of the aircraft and distributed surface incidence angle with the help of the one weakly directional antenna onboard radiolocating device B.M. Klimashov The detection of the aircraft incidence angle method, based on the isorated line form analysisis contemplated. The line is formed when the onboard radiolocating device rays the surface with a continuous signal. Radiation and reception of the signal is realized by the one weakly directional antenna and this method provides positive measurement results. The usage of the complex echo signal intercorrelation processing leads to the simplification of the surface incidence angle detection. Dopler frequencies emphasis by narrow band filters seriously decreases external noise influence. Key words: Aircraft, short-range radiolocation, incidence angle, allocated surface, near-omnidirectional antenna, Doppler frequencies, isofrequency lines, compound signal. E-mail: BMKL@SAMA.RU
