Embodiment

[0049] Such as Figure 1-6 As shown, among them, figure 2 (a) is the top view of the corner reflector, figure 2 (b) is a 45° side view, Figure 4 (a) is the front view of the concentric baffle, Figure 4 (b) is a top view of the concentric baffle, Image 6 (a) is the front view of the eccentric baffle, Image 6 (b) is the top view of the eccentric baffle. A variable RCS angle reflector provided by the present invention includes: a concentric baffle 4 , an eccentric baffle 5 and a fixed connection piece 3 .

[0050] The concentric baffle 4 is detachably connected to the fixed connector 3; the movable part of the concentric baffle 4 forms a first corner area with the surface of the fixed connector 3; the movable part of the concentric baffle 4 is adjusted to form the fixed connector 3 surface The included angle changes the size of the first corner area; the fixed part of the concentric baffle plate 4 is detachably connected to the fixed part of the eccentric baffle plate...

Abstract

The invention discloses an RCS-variable corner reflector and an unmanned helicopter target drone. The reflector comprises a concentric baffle, an eccentric baffle and a fixed connecting part; the concentric baffle is detachably connected with the fixed connecting part; a first corner area is formed between the movable portion of the concentric baffle and the surface of the fixed connecting part; the movable portion of the concentric baffle adjusts the included angle formed with the surface of the fixed connecting part to change the size of the first corner area; the fixed portion of the concentric baffle is detachably connected with the fixed portion of the eccentric baffle; a second corner area is formed by the movable portion of the eccentric baffle and the surface of the fixed connecting part; and the movable portion of the eccentric baffle adjusts the included angle formed with the surface of the fixed connecting part to change the size of the second corner area. By changing the angle between the concentric baffle and the fixed connecting part or changing the angle between the eccentric baffle and the fixed connecting part, the RCS can be variable.

Description

technical field [0001] The invention relates to the technical field of rotorcraft, in particular to a variable RCS angle reflector and an unmanned helicopter target drone. Background technique [0002] On the modern battlefield, stealth aircraft is playing an increasingly important role. The combat capability and survivability of helicopters are largely related to the radar cross section (RCS) of the helicopter. RCS is a physical quantity that characterizes the intensity of the echo generated by the target under the irradiation of radar waves. The larger the RCS, the easier it is for the target to be found by enemy radar and the weaker its survivability. [0003] In actual combat exercises, the RCS simulation of helicopter target aircraft should meet the requirements of actual combat helicopter RCS. Therefore, the simulation technology of helicopter target aircraft RCS is of great significance to modern warfare. Under normal circumstances, if a certain type of helicopter is...
