Description
Technical field
The present invention be a kind of based on active service militaryly in the face of empty Surveillance Radar and civilian air traffic control radar (being main radar), finish the radar head space and mend the backup radar of blind task, work with the main radar device synchronization, in the realization radar volume, the target of aircraft is searched for, follows the tracks of, monitored to full spatial domain non-blind area continuously automatically.
Background technology
In the face of empty Surveillance Radar and civilian air traffic control radar, all there is the upper space of silence problem in active service militaryly to some extent.In general, the upper space of silence of surveillance radar is bigger, and its blind area diameter is: 30-60km, and the blind area of guiding, air traffic control radar is less, and its blind area diameter is: 6-20km.Along with the raising of gadget technical merit and the quickening of equipment updating speed, radar terminal admission display device automaticity is more and more higher, radar intelligence (RADINT) admission reports work progressively to break away from backward situation manually to report, radar intelligence (RADINT) data transfer rate, parameter degree of accuracy are all significantly strengthened, and radar-directed admission person has been transformed into the supporting role of auxiliary works such as only finishing correction, intervention from the leading role of original information admission work.Full spatial domain non-blind area in the radar horizon is the prerequisite that realizes that the admission of radar intelligence (RADINT) whole-process automatic reports, and the radar upper space of silence has become the restriction gadget and realized that full spatial domain radar target particularly wears the head space target major obstacle of admission automatically.
The flying speed of aircarrier aircraft is generally at 900km/ hour, cruising altitude: big aircraft, 8000-12600 rice; Flivver, 6000-96000 rice; Aircarrier aircraft for 8000 meters height, the upper space of silence radius is 20km (referring to an accompanying drawing 3), as calculate (it is omnidistance by blind area diameter 40km promptly to wear radar head space airbound target) by limiting case, aircraft need fly about 2.6 minutes, for an antenna with 6 rev/mins of radars of making circular motion, this aircraft has approximately at 15 can not be found (antenna whenever circles to finding a bit), and active service in the face of the principle that empty Surveillance Radar terminal admission display device is enrolled automatically is militaryly: continuous 3 of certain a collection of target can not find promptly to be judged to disappearance, handle by fresh target when treating that it reappears, again it is compiled batch.
Existing solution is: the one, increase the start number that closes on the radar station radar, and guarantee that the effect scope covers mutually between radar; The 2nd, artificial its position of prediction of deducing for known cooperation airbound target, is handled admission person and can press both tramp-liners in the die-out time section, is predicting its position by artificial the deduction in the admission process automatically.
The problem and the influence that exist: the one, for search, supervision, the tracing task of finishing the airbound target in certain spatial domain, in the radar network composite process, must strengthen radar station cloth station density, increase on-duty radar number in the unit interval simultaneously; The 2nd, can't manually deduce prediction: supervision, the tracing task of cooperation airbound target in landing, change of flight course midway in the radar head space flight course; The 3rd, be subjected to earth curvature and the influence of thing echo doughtily, can't finish the cooperation airbound target of the low flying height of radar head space and search, supervision, the tracing task of non-cooperation airbound target.Influence that may cause and consequence: strengthen radar station cloth station density, meaning increases gadget and staffing, increases unnecessary expenses of military expenditure; For a line radar station, increase on-duty radar number in the unit interval, just increased the exposure chance of radar frequency of operation; Under the daily guarantee situation, influence the safety of air unit's battle flight training and aircarrier aircraft, cause the generation of aircraft accident; Under guarantee in the wartime situation, then may directly influence the commander, cause the loss that to retrieve to the fight of airman's opportunity of combat guiding with to the supervision of important spatial domain, important goal.
Significance of the present invention: 1, adapt to the needs of gadget development, solved active service preferably militaryly in the face of empty Surveillance Radar and civilian air traffic control radar upper space of silence problem; Number when 2, the reduction radar station is arranged density or reduced radar start number, start, this point is concerning a line radar station, just mean the exposure chance that reduces the radar frequency of operation, under the constant situation of existing weaponry and equipment quantity, increase the number of hidden radar, hidden frequency, just mean the survival probability that improves War Equipment, guarantee information high-quality, the High Data Rate of gadget in wartime, win battlefield electromagnetism initiative, have significant military affairs, economic benefit; 3, improve at ordinary times, wartime the radar intelligence (RADINT) quality assurance, alleviate radar-directed admission person's burden, realize that to greatest extent information reports robotization; 4, information reports robotization, is one of prerequisite that realizes at few man on duty or unattended radar station; 5, finish non-blind area supervision, tracking, the guiding in important goal, important spatial domain, guarantee being perfectly safe of important goal, important spatial domain.
Summary of the invention
The objective of the invention is to based on active service militaryly in the face of empty Surveillance Radar and civilian air traffic control radar, by the auxilliary radar antenna of a cover is installed at the back side of main scanner, its transmit signal power distributes acquisition by the unequal power power divider, by adjusting the sensing of auxilliary radar antenna reflecting surface, auxilliary radar feed, in the regulation elevation coverage, produce the backup radar that covers the main radar upper space of silence and mend blind coverage diagram, realize non-blind area search in full spatial domain in the radar horizon, follow the tracks of, monitor.Characteristics of the present invention: make full use of the existing common apparatus of radar, do not influence the performance and the antenna propagation characteristics of main radar, the repacking cost is low, install additional easy, the reliability height, it is obvious to mend blind effect.The present invention is applicable to that the active service of different systems is militaryly in the face of empty Surveillance Radar and civilian air traffic control radar.
