The utility model has the characteristics of high precision and high speed, and can use various weapon systems to attack hostile radar systems in real time.
Description
One, technical field
The utility model 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; 2, Air-Ground passive radar navigation system need 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 the progress situation is analyzed aspect domestic and international data fusion, a kind of method that technology such as Fuzzy Correlation, data fusion and least square are discerned 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 purpose of this utility model is to provide a kind of air-ground antiradar weapon precision-guidance system, have the advantages that precision height, speed are 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 constitutes; Radar decoy is folding stacked ball type segment angle reflector, and launch automatically the emission back; 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 input air-to-ground guided missile or other war armament systems are attacked; Laser ranging system adopts a kind of parametric laser, particularly relates to the femtosecond light parametric laser of warbling; The chirp photoparametric generator that constitutes by electric light optical beam scanner, prismatic light beam deflection device, non-linear laser crystal, laser pumping light source, reach the femtosecond photoparametric amplifier that is made of open tubular column lens or half of post 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; Simple in structure, low price, practical, can make the total solidifying laser device of ultra high power ultrashort pulse; Digital Magnetic Compass comprises three magnetic probes, triple channel magnetic amplifier, slant angle sensor and data handling system.Magnetic-field measurement is finished in three 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, handle by analysis, calculate azimuth, the angle of pitch and roll angle.Sensor signal realizes control automatically through A/D conversion input PLC controller through program, and PLC system CPU module is connected by serial line interface with the alarm indication screen, and Sensor Analog Relay System amount input module is connected by the I/O mouth, and sensor is imported PLC with related data; According to artificial judgment operation sequence establishment PLC program.
Four, description of drawings
Fig. 1 is the utility model 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 tactical missile guidance system; 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 constitutes; Radar decoy is folding stacked ball type segment angle reflector, and launch automatically the emission back; 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 input Air-Ground guided missile or other war armament systems are attacked; Laser ranging system adopts a kind of parametric laser, particularly relates to the femtosecond light parametric laser of warbling; The chirp photoparametric generator that constitutes by electric light optical beam scanner, prismatic light beam deflection device, non-linear laser crystal, laser pumping light source, reach the femtosecond photoparametric amplifier that is made of open tubular column lens or half of post 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; Simple in structure, low price, practical, can make the total solidifying laser device of ultra high power ultrashort pulse; Digital Magnetic Compass comprises three magnetic probes, triple channel magnetic amplifier, slant angle sensor and data handling system.Magnetic-field measurement is finished in three 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, handle by analysis, calculate azimuth, the angle of pitch and roll angle.Sensor signal realizes control automatically through A/D conversion input PLC controller through program, and PLC system CPU module is connected by serial line interface with the alarm indication screen, and Sensor Analog Relay System amount input module is connected by the I/O mouth, and sensor is imported PLC with related data; According to artificial judgment operation sequence establishment PLC program; Corner reflector:, have triangular corner reflector in bigger angular range, incident electromagnetic wave through triple reflection, to be reflected back by former incident direction, and produce very strong echo by the reflector that three orthogonal crossing metal flats constitute.The little corner reflector of size also has very big 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 more flat than broad, and interface rigidity is bigger, 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.
