Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

s11, monitoring electromagnetic detection signals in a protection area;
s12, according to the electromagnetic detection signals, the reflectors which are arranged in advance are adjusted so as to adjust the electromagnetic protection space; the reflectors are arranged based on topological point information determined by target distribution characteristics in a pre-acquired protection area.
It should be noted that S1N in the present specification does not represent the sequence of the distributed electromagnetic protection method, and the distributed electromagnetic protection method of the present invention is described below with reference to fig. 2-3.
S11, monitoring electromagnetic detection signals in the protection area.
It should be noted that, referring to fig. 2, the protection area includes at least one protection target and a reflector set in advance based on the protection target, where the protection target may be a communication target to be protected, such as a communication base station, a radar, etc., so as to avoid detection, interference, or destruction of the communication target by a third party.
In an alternative embodiment, before adjusting the pre-arranged reflector according to the electromagnetic detection signal, further comprises: arranging reflectors based on topological point information determined by pre-acquired target distribution characteristics in a protection area, wherein the method specifically comprises the following steps: inputting the target distribution characteristics in the protection area obtained in advance into a topology linkage model to obtain topology point information output by the topology linkage model; based on the topological point information, reflectors are arranged to form an electromagnetic shielding space.
Further, if the topology point information includes the number of topology points, the position of each topology point and the electromagnetic reflection direction of each topology point, the topology linkage model includes: the topological point determining layer is used for determining the number of topological points and the positions of the topological points according to the pre-acquired target distribution characteristics in the protection area and combining the protection radius preset for each target in the protection area and the beam coverage of a single reflector; and the direction determining layer is used for determining the electromagnetic reflection direction of each topological point according to the number of the topological points and the positions of each topological point and based on a third party detection range preset for each target in the protection area and the beam width information of the single reflector.
In other words, inputting the target distribution characteristics in the protection area acquired in advance into the topology linkage model to obtain the topology point information output by the topology linkage model, including: inputting the pre-acquired target distribution characteristics in the protection area to a topological point determining layer, and obtaining and outputting the number of topological points and the positions of the topological points by combining the protection radius preset for each target in the protection area and the beam coverage of a single reflector according to the target distribution characteristics by the topological point determining layer; the method comprises the steps of inputting the number of topological points and the positions of all topological points to a direction determining layer, and obtaining and outputting the electromagnetic reflection directions of all topological points by combining a third party detection range preset for all targets in a protection area and the beam width information of a single reflector according to the number of the topological points and the positions of all topological points by the direction determining layer.
It should be noted that determining the number of topological points and the positions of the topological points includes: acquiring position information of each target based on the target distribution characteristics; according to the position information of each target, selecting the position around each target, which accords with the preset protection radius, as an initial topological point position of each corresponding target; according to the beam coverage of the single reflector, the position of each topological point is selected from the initial topological point positions corresponding to each target, and the number of the topological points is determined. It should be noted that the beam coverage of a single reflector needs to be greater than 360/n, n representing the number of reflectors, thereby facilitating the alignment of topological points accordingly.
For example, assuming that the preset protection radius is 1 km, that is, the protection radius with the radius of 1 km needs to be formed, the position selection of the corresponding topology point needs to be considered to set the topology point about 1 km from the target.
In addition, in order to facilitate the subsequently formed protection space to meet the requirements of 360 degrees in azimuth and 90 degrees in pitching direction angles, the method for determining the electromagnetic reflection direction of each topological point comprises the following steps:
firstly, according to a preset third party detection range, determining a current topological point corresponding to each detection direction in the corresponding third party detection range. In this embodiment, the third party detection range is represented as (azimuth 360 ° and pitch angle ±90°), the detection direction is represented as (θ, Φ), where θ represents azimuth, Φ represents pitch angle, and the current topological point is represented as (k-1).
Secondly, aiming at any current topological point, taking a third party detection direction corresponding to the current topological point as an electromagnetic reflection direction of the current topological point. In this embodiment, the electromagnetic reflection direction of the current topological point is (θ, Φ), and the adjacent other topological points are denoted as k.
And finally, determining the electromagnetic reflection directions corresponding to other adjacent topological points based on the positions of the two adjacent topological points, the beam width information of the single reflector and the electromagnetic reflection directions of the current topological point. It should be noted that, referring to fig. 3, the beam width information of two adjacent topological points, the beam width information of a single reflector and the electromagnetic reflection direction of the current topological point are used to control the beam of other adjacent reflectors corresponding to the current topological point, so as to form an electromagnetic interaction area in a certain area, when a target below the electromagnetic interaction area is detected, the reflector uses the formed electromagnetic interaction area to reflect electromagnetic waves back to the third party in the same direction, so that the detection result is affected, and the electromagnetic protection function is further realized.
For example, assuming that the number of other topological points adjacent to the current topological point is 2, the electromagnetic reflection directions of the two other topological points adjacent to the current topological point are respectively represented as (θ+x, φ) and (θ -x, φ), wherein x is half of the beam width of a single reflector, so that the reflector forms a reflection beam in the azimuth [ n-x, n+x ] range, thereby effectively protecting electromagnetic detection in the third party detection range. It should be noted that the electromagnetic reflection directions of other adjacent reflectors can be analogized, and are not further described herein.
It can be seen that the i-th topological point information obtained based on the above manner is represented as L i ＝S(x i ,y i ,z i ,θ i ,φ i ) Wherein i is [1, n ]]，x i ,y i ,z i Three-dimensional position information representing the topological point; θ i And phi i The azimuth and the elevation angle are respectively indicated, and the electromagnetic reflection direction of the reflector corresponding to the topological point is indicated. According to the obtained topological point information, the reflectors are arranged to reflect the topological point electromagnetic signals, so that the formed protection space meets the azimuth 360 degrees and the pitching angle + -90 degrees.
In addition, the reflector can adopt a metamaterial reflector, and the received electromagnetic signals are modulated by utilizing the functions of echo modulation and beam modulation of the incident electromagnetic waves by using the metamaterial, so that important protection targets in the area are guaranteed to be considered, and compared with the traditional mode, the reflector is comprehensive and flexible, thereby ensuring silence and low zero power, improving the concealment and being not easy to detect. In other embodiments, the reflector may be a passive and steerable electromagnetic signal reflector, such as a corner reflector or the like.
In an alternative embodiment, in order to avoid the occurrence of protection loopholes in the electromagnetic protection in the same direction, the topology linkage model further includes: and the topological point association layer is used for associating the topological points with each other according to the topological point information. Through mutual association of topological points so as to realize linkage among the topological points, after the subsequent reflectors are arranged based on topological point information, the change of the reflecting directions of the adjacent reflectors is consistent, namely, when one of the reflectors changes, the other reflectors correspondingly change, thereby realizing linkage electromagnetic protection of regional targets, forming an electromagnetic protection space for the protection region through reasonably arranging the positions of the metamaterials and the conversion of wave beams, and ensuring that the detection radar cannot acquire real electromagnetic signal information of the targets when detecting the targets.
S12, according to the electromagnetic detection signals, the reflectors which are arranged in advance are adjusted so as to adjust the electromagnetic protection space; wherein the reflectors are arranged based on topological point information determined by the target distribution characteristics within the protected area.
In this embodiment, adjusting the pre-arranged reflectors according to the electromagnetic detection signal includes: inputting the electromagnetic detection signal into the topology linkage model to adjust the detection range of a third party by utilizing the electromagnetic detection signal so as to obtain topology point updating information output by the topology linkage model; the reflectors are adjusted using the topology point update information. Specific steps are described above and will not be further described herein.
In an alternative embodiment, after arranging or adjusting the reflectors based on the topology point information, further comprising: the reflector is powered by the power module to form an electromagnetic protection space.
