The background image is marked with the position of the radar and the defense area within the effective detection range of the radar, and in a possible implementation mode, the background image can also be marked with the effective detection range of the radar. The effective detection range of the radar refers to the range detectable by the radar, and in one example, the effective detection range of the radar can be as shown in fig. 2. The defense area is a polygonal area needing radar monitoring in the effective detection range of the radar and is used for defense arrangement of the radar area, and the defense area can be defined and set according to the actual situation. For example, if the radar needs to monitor the area where the airport a is located, the area where the airport a is located may be set as a defense area. In one example, the defense area within the effective detection range may be as shown in FIG. 3. The background image is marked with the effective detection range of the radar, so that a user can observe the effective detection range of the radar conveniently and visually, and the sub-defense area division operation of the user is facilitated.
The background image may be any image, such as a solid image or an image provided with a prescribed pattern. In one possible embodiment, the background image is an electronic map of the detection scene of the radar. The detection scene is a real world scene to be detected by the radar, the electronic map of the detection scene may directly adopt an existing electronic map, or may also be a special electronic map established for the detection scene, and the establishment mode of the electronic map may refer to a related electronic map establishment method, which is not specifically limited in the present application. In one example, the electronic map of the detection scene may be a GIS (Geographic Information System) map.
In one example, the electronic map is marked with the position of the radar, the effective detection range of the radar, and the defense area within the effective detection range of the radar. The method comprises the following steps of acquiring an electronic map of a detection scene:
the method comprises the steps of firstly, obtaining the position of a radar in a detection scene, the effective detection range of the radar and the position of a defense area in the effective detection range of the radar.
And secondly, marking the position of the radar in the electronic map of the detection scene according to the position of the radar in the detection scene.

In one example, the user may directly input the length of the cut-line radius to obtain the cut-line radius, and in one example, the cut-line radius may be obtained by the user's position of the focus of the touch screen or mouse relative to the radar.
In one possible embodiment, the obtaining the radius of the cutting line for the defence area comprises: and after receiving a cutting preparation instruction, determining the radius of the cutting line by taking the position of the radar as an origin and the position of the focus as the other end point of the radius in the background image according to the position of the current focus.

Wherein, the cutting line radius is the line segment from the radar to the focus.
In one possible embodiment, the method further comprises: and displaying the real length of the cutting line radius in the detection scene based on the scale of the background image.
The scale of the background image is similar to that of the electronic map, and is used for representing the size ratio of the effective detection range of the radar in the background image to the effective detection range of the radar in the real detection scene, and can also be understood as the size ratio of the defense area in the background image to the defense area in the real detection scene. In one example, after the focus enters the effective detection range of the radar, a corresponding arc line may be displayed according to the current focus position, where the arc line is an arc made with the radar as a center of a circle and the distance from the focus to the radar as a radius (i.e., a radius of the line). In the process of focus movement, the real length of the cutting line radius in the real monitoring scene, namely the real distance from the cutting line to the radar in the real monitoring scene, can be calculated and displayed according to the real-time scale in the background image. The display position of the real length can be set according to practical conditions in a customized mode, for example, the real length can be displayed near a focus in the background image, or the real length can be displayed near an arc cutting line in the background image, and the like.

In an example, as shown in fig. 8, for example, the defense area a is a sub-defense area, the defense area B is divided into 2 sub-defense areas by the arc cutting line, and the defense area C is divided into 2 sub-defense areas by the arc cutting line, and the early warning rule may be set only for one of the five sub-defense areas according to an actual setting requirement, or may be set for each of a plurality of sub-defense areas in the five sub-defense areas.
In a possible embodiment, the setting of the early warning rule for at least one of the plurality of sub-defense areas includes: and respectively setting early warning rules for each sub-defense area. In one example, an early warning rule may be set for each sub-defense area separately.
