[0039] The following detailed description of the embodiments of the present invention is further described in detail in conjunction with the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to exemplarily illustrate the principles of the present invention, but cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the preferred embodiments described, and the scope of the present invention is defined by the claims.

[0040] In the description of the present invention, it should be noted that, unless otherwise specified, “plurality” means two or more than two; the terms “first”, “second”, etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0041] Figure 1 A flow chart of a method for detecting and recording electromagnetic space violations provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the present invention provides a method for detecting and recording electromagnetic space violation behaviors, comprising:

[0042] Step S1, using a low noise amplifier, a multi-bandwidth filter and an automatic gain controller to detect an electromagnetic signal to obtain a target signal;

[0043] In a possible implementation, the amplification factor of the low noise amplifier is adjusted by an automatic gain controller so that the low noise amplifier amplifies the power of the electromagnetic signal according to the amplification factor, and the amplified electromagnetic signal is filtered by a filter to output the target signal. The power, frequency, bandwidth, modulation mode and duration of the target signal are analyzed. The electromagnetic signal includes ultra-wideband electromagnetic signals and narrowband electromagnetic signals.

[0044] Figure 2 The RF front-end structure diagram provided by the embodiment of the present invention is as follows: Figure 2 As shown, N parallel channels are used to receive signals within a bandwidth W. Each channel is mainly composed of a low noise amplifier, a filter and an automatic gain controller. Channel i (1≤i≤N) mainly receives signals within a bandwidth w i The sum of the bandwidths of the channels is the total received signal bandwidth, that is, w 1 +w 2 +……+w N =W. The automatic gain controller monitors the channel status. When the input signal is too large and causes saturation distortion, the automatic gain controller lowers the front-end low noise amplifier to reduce the power of the input signal. The filter needs to ensure that each channel has sufficient dynamic range and expand the expected bandwidth W by increasing the number of channels.

[0045] Step S2, determining a target signal having a violation in the electromagnetic space according to a preset rule, and obtaining a violation signal;

[0046] In a possible implementation manner, each parameter range in a preset rule is obtained; when any parameter of the target signal is not within the parameter range, the target signal is determined to be a violation signal.

[0047] Among them, the preset rules mainly refer to the spectrum allocation regulations and laws of the International Telecommunication Union and various countries.

[0048] In one example, the parameters may be wireless signal transmission power, frequency, and coverage space for fixed broadband, mobile broadband, satellite systems, voice, broadcasting, radio navigation, weather monitoring, weather forecasting, space research, earth exploration, amateur radio, and other services as specified in the International Telecommunication Union.

[0049] Step S3, using a radiation source positioning method to determine the direction and distance of the transmitting platform of the illegal signal;

[0050] In a possible implementation, a radiation source positioning method and / or a radar and / or an optical method is used to determine the position and distance of the transmitting platform of the illegal signal.

[0051] Step S4, obtaining time information and location information of the illegal signal;

[0052] In a possible implementation, time information is obtained through satellite timing or an atomic clock or a molecular clock.

[0053] In a possible implementation, longitude and latitude information is obtained through a global positioning system, astronomical knowledge, and a laser gyroscope; altitude information is obtained through a barometer or a laser gyroscope; and location information is generated based on the longitude and latitude information and the altitude information.

[0054] Step S5, extracting features of the illegal signal to obtain signal features;

[0055] In a possible implementation, an analytical signal processing method and a deep learning method are used to extract time domain features, frequency domain features, spatial domain features, cyclic spectrum domain features and joint features of the illegal signal; the joint features are composed of any two or more of the time domain features, frequency domain features, spatial domain features and cyclic spectrum domain features;

[0056] Signal features are generated according to time domain features, frequency domain features, spatial domain features, cyclic spectrum domain features and joint features.

[0057] Step S6, generating and storing a violation record based on the violation signal, the direction and distance of the transmitting platform, the time information, the location information and the signal characteristics.

[0058] In a possible implementation, the violation behavior of the violation signal is recorded in a high-dimensional space consisting of time, frequency, space, and electromagnetic space.

[0059] In a possible implementation, the violation records are stored in a distributed row storage, column storage, block storage, file storage, or object storage manner.

[0060] In a possible implementation, the violation record is compressed and encrypted before being stored.

[0061] Furthermore, the violation records may be stored periodically.

[0062] When storing data in the present invention, the sampling data of the illegal signal and its corresponding time, space and characteristic data are stored together. Figure 3 An example diagram of a violation record data structure provided by an embodiment of the present invention, such as Figure 3 As shown, first, the number of subsequent fields, the type of each field, and the length of each field are clearly defined in the file header; then the time information, location information, sampling data, and feature data are followed; and finally, the file tail is the file header and the aforementioned fields are checked and the file end flag is set.

[0063] The electromagnetic space violation detection and recording method provided by the present invention includes the steps of high-power electromagnetic signal monitoring, electromagnetic space violation detection, illegal electromagnetic signal positioning and ranging, high-precision time information acquisition, high-precision position information acquisition, signal feature extraction and identification, recording violation behavior trajectory, and rapid storage of massive electromagnetic signal data. The present invention detects and records the electromagnetic space, physical space parameters and operation trajectory of the violation signal, which is of great significance to the supervision of electromagnetic space and the regulation of electromagnetic space order.
