The invention has small volume not over 30mm3, low weight not over 1g. And it can avoid power resource to work long. The invention can match present radar, to track small motion target, as bird, etc, or track large motion target.
Description
Technical field
The present invention relates to a kind of minitype radar reflector.
Background technology
At present, the modal method of pursuit movement target is that the micro radio tracker is installed.But the radio tracking device is bigger, easily is found, and also needs power supply, can not use for a long time.Also have radar reflector is installed, as the disclosed a kind of radar reflector that is used for lifeboat of CN2515814Y.This radar reflector comprises the central shaft of a metal material, upper/lower terminal at central shaft is with four pairs of axle sleeve clamping plate rings, each is to gripping the reflection electric conductor that a slice is vertically installed on the axle sleeve clamping plate ring, four reflection electric conductors are located by the square ring of deciding of upper/lower terminal, its cross section is orthogonal " ten " font, suitable being contained on the bigger moving target.When needs are followed the tracks of bird, small-sized moving target such as winged insect, when studying their ecosystem characterization, this radar reflector is obviously inapplicable; The quality of micro radio tracker is too big, also has no idea to be installed on the target of the small-sized motion of this class.Radar generally can be found large-scale target, is because the electromagnetic wave that radar sends is returned by large-scale target reflection, is received easily.And small-sized moving target is too little owing to volume, as bird, and winged insect etc., the electromagnetic wave that radar sends is difficult for being reflected, so, be difficult to use in the target of following the tracks of the small-sized motion of this class.If at small-sized moving target radar reflector is installed, the reflection of electromagnetic wave that the energy radar sends is returned, and then can realize radar tracking.
Summary of the invention
The purpose of this invention is to provide a kind of minitype radar reflector, it can reflect the electromagnetic wave of several different frequencies, is received by radar installations easily, and volume is little, in light weight, can be installed in easily on the small-sized target, be specially adapted to tracking small-sized moving target.
A kind of minitype radar reflector of the present invention comprises positioning seat, it is characterized in that: be connected with a metal sheet on positioning seat, be connected with a lametta on metal sheet; The diameter of lametta is the 0.1-1 millimeter, and length 1-30 millimeter, lametta are solid, perhaps is hollow; The thickness of metal sheet is the 0.1-1 millimeter, and length and width all can be at the 1-30 millimeters.At least be provided with the fine rule groove on metal sheet one, the length of hachure is the 1-30 millimeter, width 0.1-1 millimeter.Metal sheet is the overall structure that a kind of material is made, and perhaps is the composite construction of unlike material.Promptly can be nonmetal with hard, make as ceramic plating, or on metallic plate, plate another kind of metal.
The present invention can be used with existing radar installations, and this existing radar installations can be launched the continuous electromagnetic wave of frequency modulation, and frequency can change in 10-3000 gigahertz scope.In the scanning of some frequency bands, it is consistent that the diameter of the lametta of minitype radar reflector and radar installations are launched electromagnetic certain frequency of this frequency band (or wavelength); In the scanning of some frequency bands, it is consistent that the length of the lametta of minitype radar reflector and radar installations are launched electromagnetic certain frequency of this frequency band (or wavelength); In some frequency band scanning, the thickness of the metal sheet of minitype radar reflector is consistent with electromagnetic certain frequency of this frequency band (or wavelength) of radar installations emission; In some frequency band scanning, the length of the metal sheet of minitype radar reflector and width, consistent with electromagnetic certain frequency of this frequency band (or wavelength) of radar installations emission; In some frequency band scanning, the length of the hachure on the metal sheet of minitype radar reflector is consistent with electromagnetic certain frequency of this frequency band (or wavelength) of radar installations emission; In some frequency band scanning, the width of the hachure on the metal sheet of minitype radar reflector, consistent with electromagnetic certain frequency of this frequency band (or wavelength) of radar installations emission.
The present invention has the following advantages: volume is little, can be no more than 30mm
3In light weight, can be below 1g; Be difficult for being found convenient the installation; Need not power supply, can long-term work.It can be installed on the precision target of motion easily; Cooperate with existing radar installations, be used to follow the tracks of the active situation of small-sized moving target, be specially adapted to study the ecosystem characterization of Xiao Wu, winged insect etc.Also can be used to follow the tracks of the active situation of large-scale moving target.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment one: referring to Fig. 1, will be by positioning seat 1, be connected on the positioning seat and be carved with the metal sheet 2 of fine rule groove 4, be connected the minitype radar reflector that lametta solid on the metal sheet 3 constitutes, the diameter of lametta is 0.3 millimeter, length is 1 millimeter, the thickness of metal sheet is 0.5 millimeter, the width of metal sheet is 1.3 millimeters, the length of metal sheet is 1.5 millimeters, the length of the fine rule groove of carving on the metal sheet is 1.2 millimeters, the width of the fine rule groove of carving on the metal sheet is 0.9 millimeter, be installed on the body of a Xiao Wu, allow it freely circle in the air, existing radar installations is mated use.The continuous electromagnetic wave of radar installations emission frequency modulation, frequency changes in 10-3000 gigahertz scope.In some frequency band scanning, it is consistent that the diameter of the lametta of minitype radar reflector and radar installations are launched electromagnetic certain frequency of this frequency band (or wavelength), in the scanning of some frequency bands, it is consistent that the length of the lametta of minitype radar reflector and radar installations are launched electromagnetic certain frequency of this frequency band (or wavelength); In some frequency band scanning, the thickness of the metal sheet of minitype radar reflector is consistent with electromagnetic certain frequency of this frequency band (or wavelength) of radar installations emission, in some frequency band scanning, the length of the metal sheet of minitype radar reflector is consistent with electromagnetic certain frequency of this frequency band (or wavelength) of radar installations emission with width; In some frequency band scanning, the length of the hachure on the metal sheet of minitype radar reflector is consistent with electromagnetic certain frequency of this frequency band (or wavelength) of radar installations emission, in some frequency band scanning, the width of the hachure on the metal sheet of minitype radar reflector is consistent with electromagnetic certain frequency of this frequency band (or wavelength) of radar installations emission.Because the length of minitype radar reflector assembly, thickness, diameter are identical with the electromagnetic wavelength that radar installations sends, stack and diffraction will take place in the ripple of several different wavelength, make radar installations be easy to receive the electromagnetic wave that reflects, can find the orientation of minitype radar reflector at the display of radar installations, also just can know and follow the tracks of the position that flies crow.
