[0042] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] An electromagnetic monitoring satellite can sense the electromagnetic field, which means that the satellite can detect the electromagnetic wave signals in the Earth's environment. In fact, almost all electronic devices and various devices equipped with electronic devices rely on electromagnetic wave signals. Even some natural phenomena on the Earth will generate certain electromagnetic wave signals. It can be seen that the perception and analysis of electromagnetic wave signals by the satellite can bring extremely broad application prospects. However, in the existing technology, the application of the electromagnetic wave signals sensed by the satellite in this field is still relatively limited, and its role has not been fully exerted.

[0044] In view of this, the present invention provides an electromagnetic signal analysis method. This method will be implemented by combining the electromagnetic wave signals collected by the electromagnetic monitoring satellite. Refer to Figure 1 As shown, it is a specific embodiment of the electromagnetic signal analysis method provided by the present invention. In this embodiment, the method includes the following steps:

[0045] Step 101: Use the electromagnetic monitoring satellite to determine the electromagnetic situation map corresponding to the target space.

[0046] In this embodiment, the target space refers to a certain macroscopic space monitored by the electromagnetic monitoring satellite, and the electromagnetic monitoring satellite can collect the electromagnetic wave signals in the target space. For the electromagnetic monitoring satellite, the target space can be the global scope or any local scope on the Earth's surface. After collecting the electromagnetic wave signals, the entire electromagnetic situation map can be obtained.

[0047] Specifically, the target space can be divided into multiple monitoring areas. A monitoring area is the space range that the electromagnetic monitoring satellite can monitor at a fixed position. When the electromagnetic monitoring satellite monitors a monitoring area, a corresponding electromagnetic spectrum can be collected. The electromagnetic spectrum depicts the specific situation of the electromagnetic wave signals in the corresponding monitoring area, including the frequency band distribution of the electromagnetic wave signals in this monitoring area and the intensity distribution of the electromagnetic wave signals.

[0048] Using an electromagnetic monitoring satellite, the electromagnetic maps corresponding to multiple monitoring regions in the target space can be determined. In one case, the electromagnetic maps of the monitoring regions can be determined when the same electromagnetic monitoring satellite passes through each monitoring region. That is, as the position of the electromagnetic monitoring satellite changes, different electromagnetic maps are obtained. In another case, multiple electromagnetic monitoring satellites at different positions can be used to separately determine the electromagnetic maps of the monitoring regions corresponding to each electromagnetic monitoring satellite. That is, through the collaborative work of each electromagnetic monitoring satellite, the electromagnetic maps corresponding to their respective positions are determined respectively.

[0049] After determining multiple electromagnetic maps, they can be further integrated into an electromagnetic situation map. Since an electromagnetic map depicts the specific situation of the electromagnetic wave signals in the corresponding monitoring region, the electromagnetic situation map depicts the specific situation of the global electromagnetic wave signals in the entire target space. Specifically, it includes the frequency band distribution of the global electromagnetic wave signals in the target space and the intensity distribution of the electromagnetic wave signals.

[0050] In some cases, each monitoring region can cover the entire range of the target space, indicating that all parts of the target space are directly electromagnetically monitored by the electromagnetic monitoring satellite. Then, at this time, directly splicing and integrating each electromagnetic map will obtain the electromagnetic situation map.

[0051] In other cases, there may be some areas in the target space that are not covered by the monitoring regions, that is, they are not directly electromagnetically monitored. This space not covered by the monitoring regions can be called a non-monitoring region. Usually, the monitoring regions will account for a relatively high proportion of the target space, and the non-monitoring regions will be surrounded by each monitoring region. So at this time, the electromagnetic map of the non-monitoring region in the target space can be further determined by using the electromagnetic map of the monitoring region. That is, through a specific algorithm, according to the situation of the partially monitored electromagnetic wave signals, the situation of the unmonitored electromagnetic wave signals is estimated. Then, based on the electromagnetic map of the monitoring region and the electromagnetic map of the non-monitoring region, the electromagnetic situation map can be spliced. For example, in some cases, the estimation of the unmonitored electromagnetic wave signals can be achieved through clustering calculations. In this embodiment, no specific limitation is imposed on such algorithms, and any algorithm that can achieve the same or similar functions can be incorporated into the overall technical solution of this embodiment.

[0052] Step 102: Determine the characteristic electromagnetic signal corresponding to the target to be analyzed.

[0053] In this embodiment, in order to fully utilize the electromagnetic wave signals sensed by the satellite, the electromagnetic situation map is first determined. Then, using this electromagnetic situation map, a certain target to be analyzed that generates electromagnetic waves in the target space can be analyzed, so as to learn some characteristics or states of the target to be analyzed.

[0054] The target to be analyzed can specifically be any artificial device or facility that can generate electromagnetic wave signals, such as ships, airplanes, ports, airports, communication equipment, electronic devices, etc.; or it can also be certain geological structures or natural objects that can generate electromagnetic wave signals, such as the moving crust, active volcanoes, thunderclouds, and so on.

[0055] The electromagnetic wave signals generated by the target to be analyzed usually have clear characteristics, and these characteristics are generally stable. For example, which frequency bands the electromagnetic wave signals are mainly distributed in, and what the intensities are in each frequency band, in what directions and angles the electromagnetic wave signals propagate, and so on. And after determining the target to be analyzed, the electromagnetic wave signals it has emitted can be used as the corresponding characteristic electromagnetic signals to represent the characteristics.

[0056] Step 103: Use a preset analysis model to determine the target electromagnetic signal corresponding to the target to be analyzed in the electromagnetic situation map according to the characteristic electromagnetic signal.

[0057] After determining the characteristic electromagnetic signal, further analysis can be carried out using artificial intelligence technology. Based on artificial intelligence technology, it can be foreseen to construct an analysis model, which can be used for the recognition and comparison of electromagnetic wave signals. Specifically, the characteristic electromagnetic signal and the electromagnetic situation map can be used as the input of the analysis model, so that the analysis model can judge whether there are some electromagnetic wave signals in the electromagnetic situation map that match the characteristic electromagnetic signal through recognition. If there are matching electromagnetic wave signals in the electromagnetic situation map, then the matching electromagnetic wave signal is determined as the target electromagnetic signal corresponding to the target to be analyzed. That is to say, it can be considered that this target electromagnetic signal is the electromagnetic wave signal actually emitted by the target to be analyzed. In other words, this proves the existence of the target to be analyzed in the target space, so the target electromagnetic signal it emits enters the electromagnetic situation map.

[0058] Thus, it is also possible to locate the target to be analyzed through the position of the target electromagnetic signal. Or further analyze based on the target electromagnetic signal to judge some current states of the target to be analyzed and predict its possible future states, etc. That is, the target electromagnetic signal is actually applied through various combinable means. This embodiment does not make any limitations in this regard.

[0059] It should be noted that the analysis model can be built and trained according to the current artificial intelligence technology. This embodiment does not make any limitations on the specific structure and training method of the analysis model. Any technology that can achieve the same or similar effects can be combined in the overall technical solution of this embodiment.

[0060] As can be seen from the above technical solutions, the beneficial effects of this embodiment are as follows: An electromagnetic monitoring satellite is used to determine an electromagnetic situation map, and based on artificial intelligence technology, operations are performed through the electromagnetic situation map to determine the target electromagnetic signals of the target to be analyzed, thereby realizing diversified analysis of the target to be analyzed; the acquisition results of the electromagnetic monitoring satellite are more fully utilized, and the role of the electromagnetic monitoring satellite is given full play to a greater extent.

[0061] Figure 1 The illustrated content is only the basic embodiment of the method of the present invention. Based on this, certain optimizations and expansions can be carried out to obtain other preferred embodiments of the method.

[0062] As Figure 2 shown, it is another specific embodiment of an electromagnetic signal analysis method of the present invention. This embodiment is further described on the basis of the foregoing embodiment. In this embodiment, the method includes the following steps:

[0063] Step 201: Use an electromagnetic monitoring satellite to determine the electromagnetic situation map corresponding to the target space.

[0064] Step 202: Determine the characteristic electromagnetic signals corresponding to the target to be analyzed.

[0065] The content in the above steps 201 to 202 is the same as that in the foregoing embodiment and will not be repeated here.

[0066] Step 203: Calculate the matching degree between multiple electromagnetic signals to be analyzed in the electromagnetic situation map and the characteristic electromagnetic signals, and determine the matching degree index of each electromagnetic signal to be analyzed and the characteristic electromagnetic signal.

[0067] The electromagnetic situation map can be regarded as a collection of a large number of electromagnetic signals, and these large numbers of electromagnetic signals are distributed according to specific positions. In this embodiment, the electromagnetic signals in the electromagnetic situation map can be called electromagnetic signals to be analyzed. Based on artificial intelligence technology, each electromagnetic signal to be analyzed is compared with the characteristic electromagnetic signal one by one, and the matching degree index between each electromagnetic signal to be analyzed and the characteristic electromagnetic signal can be calculated. This matching degree index represents the similarity between the two.

[0068] Step 204: When the matching degree index meets the preset conditions, determine the electromagnetic signal to be analyzed corresponding to the matching degree index as the target electromagnetic signal.

[0069] If the matching degree index is high enough, it means that the electromagnetic signal to be analyzed is similar enough to the characteristic electromagnetic signal, and it can be determined that the two come from the same source, that is, from the target to be analyzed. That is to say, when the matching degree index reaches a specific value, it can be considered that the preset conditions are met, and it can be determined that the electromagnetic signal to be analyzed comes from the target to be analyzed, that is, the electromagnetic signal to be analyzed can be determined as the target electromagnetic signal.

[0070] Step 205: Determine the position of the target electromagnetic signal in the electromagnetic situation map.

[0071] Step 206: Locate the target to be analyzed according to the position of the target electromagnetic signal in the electromagnetic situation map.

[0072] After determining the target electromagnetic signal in this embodiment, the position of the target electromagnetic signal in the electromagnetic situation map can be further determined. Assume that the target space is the physical space of "global scope", and there is a corresponding relationship between the electromagnetic situation map and this physical space. That is to say, the electromagnetic situation map also covers the physical space of "global scope".

[0073] The target to be analyzed can specifically be a device such as an aircraft or a ship. Determining the position of its target electromagnetic signal in the electromagnetic situation map is equivalent to determining the position of the aircraft in the physical space, thus realizing positioning based on electromagnetic wave signals.

[0074] Furthermore, the above principle can be used to analyze airports where aircraft gather and ports where ships gather. For example, calculate how many aircraft can be located at a certain airport. From this, its current busyness, route occupancy, and throughput prediction can be deduced, etc.

[0075] As Figure 3 shown, it is another specific embodiment of the electromagnetic signal analysis method described in the present invention. In this embodiment, the method includes the following steps:

[0076] Step 301: Use an electromagnetic monitoring satellite to determine the electromagnetic situation map corresponding to the target space.

[0077] Step 302: Determine the characteristic electromagnetic signal corresponding to the target to be analyzed.

[0078] Step 303: Use a preset analysis model to determine the target electromagnetic signal corresponding to the target to be analyzed in the electromagnetic situation map according to the characteristic electromagnetic signal.

[0079] The content in the above steps 301 to 303 is the same as that in the Figure 1 shown embodiment, and will not be repeated here.

[0080] Step 304: Use a preset prediction model to predict the future state of the target to be analyzed according to the target electromagnetic signal.

[0081] In this embodiment, assume that the target to be analyzed is the earth's crust. The characteristic electromagnetic signal is the electromagnetic wave signal released before the violent movement of the crust (i.e., earthquake) collected in the past. That is to say, when such electromagnetic wave signals appear, an earthquake can be predicted.

[0082] After determining the electromagnetic situation map, it is possible to comprehensively analyze whether there is an electromagnetic signal matching the characteristic electromagnetic signal at a certain position. If so, it can be determined as the target electromagnetic signal. Further, it is possible to judge the position where the target electromagnetic signal appears, and it is likely that a violent crustal movement will occur and the earthquake risk is relatively high. That is, the future state of the target to be analyzed is predicted.

[0083] As Figure 4 shown, it is a specific embodiment of the electromagnetic signal analysis device described in the present invention.
