Abstract
The utility model provides a calibrator of a radar reflector, which comprises an installation platform. A global positioning system (GPS) antenna, a short-wave antenna, a GPS power source, a GPS receiver and a short-wave radio capable of realizing real-time transmission of measured GPS data. The calibrator is characterized in that a balloon is connected to the upper end of the installation platform while a triangular interface reflector is connected to the lower end of the installation platform, the lower end of the triangular interface reflector is connected with one end of a rope, and the other end of the rope is connected to the ground. The calibrator is used for dynamic and static alignment of distance, position and elevation zero position of various radars, solves the problem that conventional calibrators fail to realize elevation alignment, and can realize distance, position and elevation alignment of radars on wharfs without conditions for erecting radar reflectors in the past.
Description
Technical field
The utility model belongs to the ship combat system zero-bit to the locating tab assembly applied technical field.
Background technology
The zero-bit aligning is an important link in the warship development process, is the key work that fully guarantees the ship detection service ability.It is the important content of system alignment that the zero-bit of warning detection radar is aimed at, tradition generally is to demarcate the method for thing with surveying special-purpose radar corner reflector, radar corner reflector is demarcated thing can be erected at land opening or exposed waters, have the shipyard of better natural condition and the base cost that costs a lot of money individually and set up land or marine special-purpose corner reflector pylon, radar corner reflector has been installed, guaranteed the aligning of radar pack parameter to a certain extent, variation along with development of economic construction and environmental baseline, some radar corner reflectors of having set up have also lost use value, but a lot of shipyards and base do not have the condition that the frame special radar set is established corner reflector, can't effectively implement the alignment work of radar; In addition, can also do the aligning that target is carried out radar with towboat, but the towboat target is big, is difficult to determine the reflection kernel position, alignment precision is had certain influence; Above-mentioned two kinds of methods generally can only be carried out the aligning of position angle and distance, also can't satisfy the requirement, particularly three-dimensional radar of aiming at the warning detection radar elevation angle, multifunction array radar to alignment request.Chang Gui GPS measuring method all needed to resolve the precision that could obtain centimetre-sized as static state, rapid static, kinetic measurement afterwards in the past.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of radar reflector to demarcate thing, can be applied to the dynamic and static alignment of distance, orientation and elevation angle zero-bit of various radars, solve and demarcated the problem that thing can't carry out elevation angle aligning in the past.
The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be: a kind of radar reflector is demarcated thing, comprise mounting platform, mounting platform is provided with the short-wave radio set of gps antenna, short-wave antenna, GPS power supply, GPS receiver and real-time Transmission gps measurement data; It is characterized in that: the mounting platform upper end connects balloon, lower end linkage triangle shape boundary reflection device; Triangle boundary reflection device lower end connects with hawser one end, and the other end of hawser connects with ground.
Press such scheme, described balloon is made up of spheroid, nose cone, drag-line, pressure conditioning equipment and power supply management device, and the balloon afterbody is furnished with down " Y " type tail, fills helium in the spheroid, fills pressurized air in the empennage.
Press such scheme, described triangle boundary reflection device is made by orthogonal rigidly connected metal flat.
Press such scheme, connect by electric capstan between described hawser and the ground, electric capstan is made up of storage rope reel, motor and turbine worm speed reduction unit.
Press such scheme, described mounting platform is the rectangular box that steel plate is made, and welded top has gps antenna mounting base and short-wave antenna mounting base; Described gps antenna is installed on the gps antenna mounting base, and described short-wave antenna is located on the short-wave antenna mounting base; Be provided with the fixedly high strength rubber band of GPS receiver and GPS power supply in the described mounting platform.
Principle of work of the present utility model and process are: balloon is mainly used in carrying mounting platform and triangle boundary reflection device, and keeps radar reflector demarcation thing to go up to the air, and forms an isolated airborne radar target; Mounting platform is mainly used in installs gps antenna, short-wave antenna, GPS power supply, GPS receiver and short-wave radio set, the GPS receiver is the key component of demarcating thing, assurance provides accurately the demarcation thing real time position with time coordinate, carries out the comparison of zero-bit data for radar; The effect of triangle boundary reflection device is exactly to strengthen the reflecting properties of demarcating thing, and it is the reflection barycenter that radar reflector is demarcated thing; Short-wave radio set is used for the real-time Transmission gps measurement data, supports the gps system real time dynamic measurement; Hawser and electric capstan are used to draw balloon, and be fixed on the appropriate location, ground, the length of hawser can be discharged requirement for height according to balloon and be determined, to guarantee that the balloon type radar reflector has enough elevations angle with respect to radar, the convenient dispensing height of adjusting balloon type radar reflector demarcation thing of electric capstan.
The beneficial effects of the utility model are: the dynamic and static alignment of distance, orientation and elevation angle zero-bit that 1, is used for various radars; 2, the problem that thing can't carry out elevation angle aligning was demarcated in solution in the past; 3, also can carry out distance by radar, orientation and the elevation angle at the harbour that does not set up the radar reflector condition in the past aims at.
