Description
Technical field
The invention belongs to corner reflector, and in particular to a kind of new low fluctuating RCS corner reflectors of wide angle.
Background technology
, it is necessary to develop various forms of target simulators, sometimes in the Electromagnetic Scattering Characteristics for simulating various realistic objectives
It is required that the RCS fluctuating scopes of target simulator are smaller.General target simulator is all by multiple triangular corner reflectors（As schemed
（1）It is shown）The array of composition, in order to meet the requirement of target simulator spatial coverage, what is typically considered is with corner reflector
(effective coverage of single corner reflector), so setting in target simulator in 3dB teachings on the basis of maximum direction
During meter, the RCS as caused by single corner reflector, which rises and falls, just 3dB, and on the basis of corner reflector maximum direction
The space multistory angle of 3dB teachings (effective coverage of single corner reflector) covering is limited, if it is desired to which spatial dimension is larger
Target simulator, it is necessary to corner reflector number of unit it is more, corresponding cost also just improve.
But the RCS values of this corner reflector are unsatisfactory, it is impossible to meet actual demand.
The content of the invention
The purpose of the present invention is that there is provided a kind of low fluctuating RCS corner reflectors of wide angle for prior art defect.
What the present invention was realized in：A kind of low fluctuating RCS corner reflectors of new wide angle, including mutually perpendicular three
Face, length L is taken in mutually handing in for two sides, and length L is taken on three intersections, and three intersections are described for convenience and are referred to as
The length on the side of side, i.e., three is L；
Identical shape is respectively provided with three faces, the shape is removed based on triangle on the bottom surface of triangle
One is trapezoidal, and the base of triangle and the angle of intersection are 34~40 °, the trapezoidal upper bottom edge length removed be 0.2L~
The angle of 0.3L, trapezoidal base and hypotenuse is 40~50 °, and the length of hypotenuse is 0.3L~0.4L, and the position of the trapezoidal setting is
Ground center, it is ensured that what is ultimately formed is shaped as axisymmetric shape.
It is using effect of the invention：The coverage of corner reflector effective coverage is increased, target simulator is improved
Precision in design process, provides flexible and changeable method for the development of later target simulator, is target simulator development
The middle quantity for reducing triangular corner reflector, it is cost-effective to provide technical support, with important engineering application value.

Embodiment
As shown in accompanying drawing 2 and accompanying drawing 3, a kind of new low fluctuating RCS corner reflectors of wide angle, including mutually perpendicular three
Face（Similar corner）, length L is taken in mutually handing in for two sides, length L is taken on three intersections, three phases are described for convenience
The length that cross surface is referred to as the side of side, i.e., three is L.
Identical shape is respectively provided with three faces, the shape is removed based on triangle on the bottom surface of triangle
One is trapezoidal, and the base of triangle and the angle of intersection are 34~40 °, the trapezoidal upper bottom edge length removed be 0.2L~
The angle of 0.3L, trapezoidal base and hypotenuse is 40~50 °, and the length of hypotenuse is 0.3L~0.4L, and the position of the trapezoidal setting is
Bottom center, it is ensured that what is ultimately formed is shaped as axisymmetric shape.
As shown in Figure 6, the RCS values of the application corner reflector are well more many than the RCS values effect of traditional corner reflector.
