Problems solved by technology

The current reflector used on the target is a metal plate. Such a reflector can only reflect electromagnetic waves, so that when a target with such a structure reflector is detected by the radar, the radar can only show one The characteristics of the radar reflection wave of the state, so it is easy to be detected and identified by the radar, and the security is extremely poor

Embodiment Construction

[0026] Such as figure 1 , figure 2As shown, a digitally programmable Luneberg lens reflector of this embodiment includes a Luneberg lens 1, a reflector array 100 and a control unit, and the reflector array 100 includes several working states that can transmit electromagnetic waves and reflect electromagnetic waves The reflectors 2 switched between, the fronts of these reflectors 2 are set facing the direction of the Lunberg lens 1; each reflector 2 is connected to the control unit, and the control unit controls the working state of the reflector 2 through the output bias voltage . When in use, the reflector array 100 is composed of several reflectors 2 as a whole, and the reflectors 2 are distributed according to a certain rule or randomly in the reflector array 100 . Each reflector 2 can be in a transmission state or a reflection state. The so-called reflective state refers to a state in which the electromagnetic wave is irradiated on the reflector 2, and the reflector 2 c...

Abstract

The invention relates to a digital programmable Luneberg lens reflector which is characterized by comprising a Luneberg lens, a reflector array and a control unit, the reflector array comprises a plurality of reflecting plates, the working states of the reflecting plates can be switched between transmission electromagnetic waves and reflection electromagnetic waves, and the front faces of the reflecting plates all face the direction where the Luneberg lens is located; the reflecting plates are connected with the control unit, and the control unit controls the working states of the reflecting plates through the output bias voltage. The reflector has the advantages of simple and scientific structure, stability, reliability, simplicity and convenience in operation and the like.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a digital programmable Luneberg lens reflector. Background technique [0002] Radar is an electronic device that uses electromagnetic waves to detect objects. The radar emits electromagnetic waves to irradiate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), azimuth, and height. The reflection characteristics of the electromagnetic waves detected by the radar, just like the identity information of the equipment, can be detected and identified by the radar. Different equipment has different radar reflection characteristics. The current reflector used on the target is a metal plate. Such a reflector can only reflect electromagnetic waves, so that when a target with such a structure reflector is detected by the radar, the radar can...
