Abstract
The invention discloses a method and a device for finding a stealth aircraft, which mainly adopt an antenna or a telescope to collect cosmic rays or radio waves or rays or infrared signals from the space, a receiver processes and converts the signals into the recordable and displayable form, a terminal device records the signals, processes and displays the signals according to specific requirements; when the stealth aircraft or other aircrafts fly by the region, the receival of the signals is blocked in a short time, a computer can analyze and sort the differences of the signals to find the aircrafts, then the aircrafts which are found by a radar are eliminated by being matched with the radar for use, the remaining is the stealth aircraft; the invention provides the effective and cheap method and the device which can detect the stealth aircraft, thereby providing huge contribution to China's national defense construction.
Description
One, technical field
The invention belongs to the astrosurveillance technical field, belong to Detection Techniques field especially latent row aircraft.
Two, background technology
Radio telescope is a basic equipment of surveying the celestial radio radiation.Can measure intensity, frequency spectrum and the polarization equivalent of celestial radio.Usually, constitute by antenna, receiver and terminal device 3 parts.Antenna is collected the radio radiation of celestial body, receiver with these signals processing, changing into can be for record, the form that shows, terminal device gets off signal record, and carries out some processing by specific requirement and show then.The basic index that characterizes the radio telescope performance is spatial resolution and sensitivity, and the former reflects the ability of distinguishing radio point source close to each other on two celestial spheres, and the latter is reflected the ability of surveying faint radio source.Radio telescope requires to have high spatial resolution and high sensitivity usually.Difference according to the antenna general structure, radio telescope can be divided into filled aperature and discontinuous aperture two big classes, the former main representative be adopt the single-deck parabola antenna through the canonical form radio telescope, the latter is the various Combined Antenna Systems based on interference technique.Produced two kinds of novel discontinuous aperture radio telescope---very long baseline interferometer and synthesis radiotelescopes the sixties in 20 century, the former has high spatial resolution, and the latter can obtain radio map picture clearly.But Zui Da following-up type reaches 100 meters through its parabola antenna diameter of canonical form radio telescope in the world, is installed in this Planck radio astronomy research institute of German mark; Zui Da discontinuous aperture radio telescope is a very large array in the world, is installed in the state-run radio observatory of the U.S..
(historical brief introduction)
1931, in the Bell Laboratory of N.J., be responsible for the American KG Yang Si base of special search and discriminating phone undesired signal and find: a kind of peaked radio interference that occurred every 23 hours 56 minutes 04 second is arranged.Through anatomizing, he asserts in the article of delivering in 1932: this be from the milky way in radio radiation.Thus, Yang Siji has started the new era with radio wave research celestial body.He used at that time is long 30.5 meters, high 3.66 meters rotating antenna battle array, has obtained wide " fan-shaped " direction bundle of 30 degree in 14.6 metric wave length.After this, the history of radio telescope is the history that improves constantly resolution and sensitivity.
After Yang Siji announced to receive the radio signal of the milky way, American G thunder uncle manufactured experimently radio telescope with great concentration, makes successfully in nineteen thirty-seven finally.This is a unique parabolic shape radio telescope in the whole world before World War II.Its parabola antenna diameter is 9.45 meters, has obtained " pencil shape " direction bundles of 12 degree in 1.87 metric wave length, and has measured the radiowave that the sun and some other celestial body send.Therefore, the thunder uncle initiator of parabolic shape radio telescope that is known as.
Radio telescope is observation and the research basic equipment from the radio wave of celestial body, and it comprises: collect the directional antenna of radio wave, amplify the high sensitive receiver of radio signal, the information record is handled and display system or the like.The ultimate principle of radio telescope is similar with the optical reflection telescope, the electromagnetic wave that projection comes by an accurate direct reflection after, homophase arrival public focus.Be easy to realize the homophase gathering with the paraboloid of revolution as minute surface.Therefore, the antenna of radio telescope is parabolic mostly.
Radio observation is to carry out in very wide frequency range, and the radio technology of detection and information processing is uncommon versatile and flexible than the optics ripple again, so the radio telescope kind is more, sorting technique is varied.For example the shape by receiving antenna can be divided into parabola, parabolic cylinder, sphere, the parabolic radio telescopes such as band, loudspeaker, spiral, row ripple, antenna that cut; Can be divided into radio telescopes such as pencil beam, fan-beam, multi beam by the direction harness shape; Can be divided into mapping, location, calibration, polarization, frequency spectrum, radio telescope such as resemble day by the observation purpose; The radio telescope that can be divided into types such as total power, frequency sweep, fast imaging by job category again.
