Abstract
The invention discloses one kind from record position radar calibration metal ball, including metal ball, GPS, lithium battery and interface circuit；The GPS, lithium battery and interface circuit are located in metal ball, after metal ball is sealed, and GPS input radio frequency antenna is connected to GPS thin slice ceramic antenna from metal ball Base top contact, and thin slice ceramic antenna is fixed at the top of metal ball；The charging wire of the lithium battery and the location data output line of GPS are connected on the socket at the top of metal ball.The radar beam that the present invention can solve traditional metal ball as Scattering Targets and exist points to the low technical problem of positioning precision.
Description
Technical field
The present invention relates to a kind of calibration technology of radar.
Background technology
By the use of metal ball as Scattering Targets, a kind of radar calibration method that radar calibration is standard is carried out.Usually use
Balloon, aircraft hang a metal ball, and when metal ball enters radar detection wave beam, scattering of the radar with regard to that can detect metal ball is believed
Number, because the scattering section RCS of metal ball is known, therefore radar can be calibrated with metal ball.Here metal ball
It is standard garden ball empty in one.Influence in order to avoid other objects to radar calibration, the device of positioning（Such as GPS）
Need to leave the segment distance of metal ball one, usually tens meters.Device is positioned such that not in radar beam, radar would not be also allowed
The scattered signal of positioning devices is received, intensity calibration precision is not interfered with, but the position that positioning devices are obtained is not real
Metal ball position, radar beam point to positioning precision will reduce.Existing metal ball calibration is less than accurate metal ball position
And speed.
The content of the invention
It is an object of the invention to provide one kind from record position radar calibration metal ball, made with solving traditional metal ball
The low technical problem of positioning precision is pointed to for the radar beam that Scattering Targets are present.
In order to realize foregoing invention purpose, the technical solution adopted in the present invention is as follows：
It is a kind of from record position radar calibration metal ball, including metal ball, GPS, lithium battery and interface circuit；It is described
GPS, lithium battery and interface circuit be located at metal ball in, after metal ball is sealed, by GPS input radio frequency antenna from
Metal ball Base top contact is connected to GPS thin slice ceramic antenna, and thin slice ceramic antenna is fixed at the top of metal ball；The lithium battery
Charging wire and the location data output line of GPS be connected on the socket at the top of metal ball.
The present invention is a little：
（1））The position of metal ball can accurately be obtained
（2））The translational speed of metal ball, calibration doppler velocity can be obtained.

Fig. 2 is Fig. 1 top view.
Numbered in figure：1st, charging, signal plug, 2, charging, signal wire, 3, lithium battery, 4, GPS and circuit board,
5th, metal ball, 6, radio frequency line, 7, gps antenna, 8, suspension line.
Embodiment
The structure of the present invention is referring to shown in Fig. 1,2.
The present invention has shielding action using metal ball, is placed on when other metals in metal ball, would not be by
The outer electromagnetic wave irradiation of metal ball, produces scattering.GPS, lithium battery and interface circuit are put into metal ball, then gold
Belong to that ball sealing is good, and GPS input radio frequency wire antenna be connected to GPS thin slice ceramic antenna from metal ball Base top contact,
Thin slice ceramic antenna is fixed at the top of metal ball.Lithium cell charging line and GPS location DOL Data Output Line are connected to metal simultaneously
On the socket in top dome portion.
Fig. 1,2 are from record position radar calibration metal ball structural representation.In metal ball bottom equipped with GPS,
Lithium battery and interface circuit.GPS and gps antenna complete metal ball positioning, and by location information（Time, longitude, latitude
Degree, height）It is stored in the storage of interface circuit wherein.Lithium battery is the power supply of GPS and interface circuit.Interface circuit is used for
GPS location information is stored, lithium cell charging is managed and is communicated with the computer outside metal ball, export GPS location information.Charging,
Signal wire socket, for being communicated to lithium cell charging and computer with interface circuit.Suspension strop is used for hanging metal ball, by outstanding
Metal ball can be suspended under balloon or aircraft by lanyard.
The workflow of the present invention：
（1）By charging, signal plug to lithium cell charging.
（2）After lithium battery is fully charged, GPS is started working, and metal ball is suspended on into lift-off platform（Balloon, nothing
It is man-machine etc.）, if unmanned plane, metal ball is needed 100 meters below unmanned plane.
（3）Leaving the place of radar certain distance, lift-off platform carries metal ball lift-off, split 100- from the ground
500 meters, radar begins look for metal ball.
After radar is collected into certain amount metal ball signal, lift-off platform landing, computer passes through charging, signal plug
Connecting interface circuit, takes out location information.
