Abstract
The invention discloses an air-ground antiradar weapon precision-guidance system which comprises a radar decoy, a wide-frequency radar receiver, an azimuth angle and pitch angle measuring device that is a digital magnetic compass, a laser distance measuring device, a GPS device and a PLC automatic control system. The air-ground antiradar weapon precision-guidance system has the characteristics being high in accuracy and rapid in speed, and using multiple tactical weapon systems for attacking an enemy radar system in real time.
Description
One, technical field
The present invention relates to a kind of air-ground antiradar weapon precision-guidance system.
Two, background technology
The problem that existing counter radar weapon exists: 1, anti-interference, the anti-shutoff capability of antiradar missile is not strong, and attack pattern is single; Air-Ground passive radar navigation system need to repeatedly be sampled the radiation source parameter is estimated, accuracy, real-time are poor.For example: the Li Hong of guided missile institute of air force engineering university is " Research on parameter recognition of enemy radar " just, on the basis that domestic and international data fusion progress situation is analyzed, a kind of method that the technology such as Fuzzy Correlation, data fusion and least square are identified the concrete coordinate of unknown Radar emitter of using has been proposed, for the data that further merge unknown source lay the first stone.Simulation result shows, and is along with the increase of sampled data, more accurate to the estimation meeting of radiation source parameter.
Three, summary of the invention
The object of the present invention is to provide a kind of air-ground antiradar weapon precision-guidance system, have the advantages that precision is high, speed fast, can use multiple Tactical Weapon System that the enemy radar system is hit in real time, comprise radar decoy, broadband radar receiver, azimuth, angle of pitch measurement mechanism are Digital Magnetic Compass, laser ranging system, the GPS device, the PLC automatic control system consists of; Radar decoy is folding stacked ball type segment angle reflector, Automatic-expanding after the emission; After the broadband radar receiver received the enemy radar signal, Digital Magnetic Compass, laser ranging system, GPS measurement device went out azimuth, the angle of pitch, distance, calculate the enemy radar coordinate, and the input air-to-ground guided missile is attacked; Laser ranging system adopts a kind of femtosecond optical parametric laser instrument of warbling; The chirp photoparametric generator that is consisted of by electric light optical beam scanner, prismatic light beam deflection device, non-linear laser crystal, laser pumping light source, reach the femtosecond optical parametric amplification device that is made of open tubular column lens or half side column lens, non-linear laser crystal, pump light source and chirped light pulse shortener, both are in conjunction with forming ultrashort-pulse chirp photoparametric laser device; Can make the All solid state of ultra high power ultrashort pulse; Digital Magnetic Compass comprises three axle magnetic probes, triple channel magnetic amplifier, slant angle sensor and data handling system; Magnetic-field measurement is finished in three axle magnetic probes and the combination of triple channel magnetic amplifier, slant angle sensor is finished the incline measurement of both direction, it is the measurement of the angle of pitch and roll angle, the analog quantity of measuring is converted to digital quantity through data handling system, process by analysis, calculate azimuth, the angle of pitch and roll angle; Sensor signal is through A/D conversion input PLC automatic control system, realize automatically control through program, PLC automatic control system CPU module is connected with alarm indication by serial line interface and is connected, and Sensor Analog Relay System amount input module is connected by the I/O mouth, and sensor is inputted the PLC automatic control system with related data; According to artificial judgment operation sequence establishment PLC automatic control system program.
Four, description of drawings
Fig. 1 is this patent structure principle chart.
Five, specific embodiment
Introduce specific embodiment below in conjunction with accompanying drawing: in Fig. 1,1 is Digital Magnetic Compass; 2 is the GPS device; 3 is laser ranging system; 4 is the PLC automatic control system; 5 is Air-Ground tactics missile brains; 6 is the radar decoy device.A kind of air-ground antiradar weapon precision-guidance system comprises radar decoy, broadband radar receiver, and azimuth, angle of pitch measurement mechanism are Digital Magnetic Compass, laser ranging system, and the GPS device, the PLC automatic control system consists of; Radar decoy is folding stacked ball type segment angle reflector, Automatic-expanding after the emission; After the broadband radar receiver received the enemy radar signal, Digital Magnetic Compass, laser ranging system, GPS measurement device went out azimuth, the angle of pitch, distance, calculate the enemy radar coordinate, and the input air-to-ground guided missile is attacked; Laser ranging system adopts a kind of femtosecond optical parametric laser instrument of warbling; The chirp photoparametric generator that is consisted of by electric light optical beam scanner, prismatic light beam deflection device, non-linear laser crystal, laser pumping light source, reach the femtosecond optical parametric amplification device that is made of open tubular column lens or half side column lens, non-linear laser crystal, pump light source and chirped light pulse shortener, both are in conjunction with forming ultrashort-pulse chirp photoparametric laser device; Can make the All solid state of ultra high power ultrashort pulse; Digital Magnetic Compass comprises three axle magnetic probes, triple channel magnetic amplifier, slant angle sensor and data handling system; Magnetic-field measurement is finished in three axle magnetic probes and the combination of triple channel magnetic amplifier, slant angle sensor is finished the incline measurement of both direction, it is the measurement of the angle of pitch and roll angle, the analog quantity of measuring is converted to digital quantity through data handling system, process by analysis, calculate azimuth, the angle of pitch and roll angle; Sensor signal is through A/D conversion input PLC automatic control system, realize automatically control through program, PLC automatic control system CPU module is connected with alarm indication by serial line interface and is connected, and Sensor Analog Relay System amount input module is connected by the I/O mouth, and sensor is inputted the PLC automatic control system with related data; According to artificial judgment operation sequence establishment PLC automatic control system program.Corner reflector: by the reflector that three orthogonal crossing metal flats consist of, have the triangular corner reflector can be in larger angular range, the electromagnetic wave of incident through triple reflection, is reflected back by former incident direction, and produces very strong echo.The little corner reflector of size also has very large radar cross section.Maximum radar cross section depends primarily on the accuracy that keeps the right angle between each face of reflector, and small angular deviation and plate face injustice all will cause significantly reducing of radar cross section.The directional diagram of corner reflector is about 25 °～50 °.The directional diagram of triangular corner reflector is wider flat, and interface rigidity is larger, and manufacturing requires also not high.
Native system can use unmanned plane delivery, near emission radar decoy when flying to enemy's air defense radar, the start of temptation enemy radar, attack, system measures accurate coordinates in real time through calculating, input Air-Ground guided missile, antiradiation missile guidance system perhaps are transferred to coordinate data the ground Tactical Weapon System enemy's air defense radar are attacked.
