[0041] Example 1

[0042] An ultra-short wave communication interference source device based on a launch platform, including an airborne device carried on a drone, the airborne device including a reconnaissance excitation integrated machine, a power amplifier module, an interference module and an antenna, the antenna including a direction-finding antenna and a reconnaissance antenna, wherein the reconnaissance antenna includes a 30-520MHz transceiver integrated antenna and a 520-3000MHz receiving antenna. Generally speaking, when performing a direction-finding task, the signal comes from the direction-finding antenna (cross-loop antenna); when performing a reconnaissance task, the signal comes from the reconnaissance antenna. When used portable in wartime, the direction-finding antenna is shared by both the direction-finding task and the reconnaissance task.

[0043] The reconnaissance and excitation integrated machine is mainly composed of a direction finding channel unit, a reconnaissance channel unit, an excitation channel unit, a data acquisition unit, and a signal processing unit. The radio frequency signal collected by the direction finding antenna is input into the data acquisition unit via the direction finding channel unit and / or the reconnaissance channel unit. The radio frequency signal collected by the reconnaissance antenna is input into the data acquisition unit via the reconnaissance channel unit. The data acquisition unit is connected to the signal processing unit. Figure 1 shown.

[0044] The signal processing unit is used to perform corresponding operations according to the training tasks issued by the command center; when the command center issues an interference command, the reconnaissance excitation integrated machine generates a corresponding excitation signal and outputs it to the outside through the excitation channel unit, the power amplifier module, and the reconnaissance antenna. The interference module is used for antenna tuning and power amplifier calibration.

[0045] In order to achieve the orderly integration of various training tasks involved in ultra-short wave communication military training, according to different training tasks, the channel has 6 working modes, namely direction finding working mode, reconnaissance working mode, reconnaissance direction finding mode, frequency hopping tracking / smart jamming mode, frequency band / frequency guided jamming mode, and forced jamming mode. In the direction finding working mode, only the direction finding channel unit works; in the reconnaissance working mode, only the reconnaissance channel unit works; in the reconnaissance direction finding mode, the direction finding channel and the reconnaissance channel work at the same time; in the frequency hopping tracking / smart jamming mode, the reconnaissance channel and the excitation channel work at the same time; in the frequency band / frequency guided jamming mode, the reconnaissance channel and the excitation channel work time-sharing; and in forced jamming, only the excitation channel works.

[0046] At the same time, the signal processing unit has 6 working states, namely conventional reconnaissance, specific signal reconnaissance, channel reconnaissance, frequency hopping signal reconnaissance, frequency hopping tracking interference guidance, and smart interference guidance; different working states are realized by the cooperation of different task modules in the signal processing unit, which include broadband reconnaissance task module, narrowband analysis task module and direction finding task module.

[0047] During conventional reconnaissance, the broadband reconnaissance task module performs broadband spectrum calculation and broadband baseband data output of signals within the instantaneous processing bandwidth; the narrowband analysis task module performs analysis, identification, decoding / demodulation and narrowband baseband data output of narrowband signals; the direction finding task module performs simultaneous direction finding of multiple signals within the instantaneous processing bandwidth. The operator control terminal displays and records the data transmitted by the reconnaissance excitation integrated machine, such as Figure 2 shown.

[0048] During the specific signal reconnaissance process, the broadband reconnaissance task module performs broadband search for known signals within the instantaneous processing bandwidth; the narrowband analysis task module performs narrowband signal analysis and identification based on the broadband search results; and the direction finding task module performs simultaneous direction finding for multiple signals within the instantaneous processing bandwidth. The operator control terminal displays and records the data transmitted by the reconnaissance excitation integrated machine, such as Figure 3 shown.

[0049] During the channel reconnaissance process, the broadband reconnaissance task module performs a rapid search for broadband signals; the narrowband analysis task module performs narrowband signal analysis and identification based on the broadband search results (i.e., the intercepted signals); and the direction finding task module performs narrowband direction finding based on the broadband search results (i.e., the intercepted signals). The operator control terminal displays and records the data transmitted by the reconnaissance excitation integrated machine, such as Figure 4 shown.

[0050] During the frequency hopping signal reconnaissance process, the broadband reconnaissance task module performs broadband spectrum calculation and frequency hopping signal search within the instantaneous processing bandwidth; the direction finding task module performs broadband direction finding based on the frequency hopping search results (i.e., sorting results). The operator control terminal displays and records the data transmitted by the reconnaissance excitation integrated machine, such as Figure 5 shown.

[0051] During the frequency hopping tracking interference guidance process, the broadband reconnaissance task module sets the tracking interference parameters and establishes the background threshold according to the frequency hopping signal parameters set by the operator at the control end, and then searches for the frequency hopping signal. After searching for the frequency hopping signal, the interference module is quickly guided to achieve tracking interference of the frequency hopping signal. Figure 6 shown.

[0052] During the smart jamming guidance process, the narrowband analysis task module demodulates / decodes the smart jamming parameters set by the operator at the control end, and after detecting the synchronization frame or key frame, the smart jamming is implemented through the jamming module, such as Figure 7 shown.

[0053] By using a launch platform (i.e., a drone) that is easy to control the rise and fall and orientation of the airborne equipment, it is necessary to control the size and weight of the airborne equipment and streamline the hardware configuration so that it can be carried by the launch platform.

[0054] In order to simplify the channel, the direction finding channel unit and the reconnaissance channel unit are receiving channels, and adopt a superheterodyne secondary frequency conversion structure, such as Figure 8 As shown, the first intermediate frequency is 4400MHz, the second intermediate frequency is 140MHz (bandwidth 60MHz), the internal reference clock is 204.8MHz, the output frequency range of the first local oscillator is 4460-7400MHz; the output frequency of the second local oscillator is 4260MHz.

[0055] The excitation channel unit includes an output channel, which adopts a secondary mixing structure, such as Fig. 9 The 140MHz intermediate frequency signal is mixed with two local oscillators to obtain an intermediate frequency, which is then mixed with a local oscillator to obtain a 30-520MHz excitation signal and output.

[0056] The receiving channel is respectively connected to the three sampling channels of the data acquisition unit, and the excitation output channel is connected to the one digital-to-analog conversion channel of the data acquisition unit; the three data acquisition channels all use a high-speed analog-to-digital converter LTC2107, and the one digital-to-analog conversion channel uses a high-speed digital-to-analog converter AD9788. Fig.10 The sampling clock uses an external reference clock or a local clock, and generates 4 sampling clocks through a one-to-four splitter, which are provided to three high-speed analog-to-digital converters LTC2107 and one high-speed digital-to-analog converter AD9788 respectively.

[0057] In order to integrate direction finding, reconnaissance and interference, the signal processing unit is mainly composed of FPGA and DSP. Fig.11As shown. The FPGA is bidirectionally connected to the data acquisition unit for data preprocessing and packaging all data for transmission to the DSP to reduce the workload of the DSP. The DSP uses an 8-core digital signal processor TMS320C6678 to perform corresponding operations according to the training tasks issued by the command center. To ensure the smooth execution of various tasks, each core is assigned to a specific work task to ensure the smooth progress of various tasks. For example, core 0 is the control DSP, which is used for data reception, distribution and result uploading; core 1 is used for direction finding processing and broadband FFT calculation of two direction finding channels; core 2 is used for wide- and narrow-band direction finding functions; core 3 is used for narrow-band direction finding, narrow-band filtering, and narrow-band FFT calculation; cores 4 and 5 are used for frequency hopping signal search and broadband conventional signal search, and cores 6 and 7 are used for analysis, demodulation / decoding and protocol recognition of narrow-band signals. The internal implementation block diagram of the DSP is shown below. Fig.12 shown.

[0058] FPGA converts the control signal transmitted by DSP through EMIF interface into SPI signal for channel control, antenna control, power amplification control and analog-to-digital conversion and digital-to-analog conversion configuration of digital acquisition unit. The reconnaissance excitation integrated machine is provided with an interface unit to facilitate the signal communication between the signal processing unit and other components.

[0059] The FPGA includes two data preprocessing channels, namely the direction finding channel and the reconnaissance channel. The direction finding channel completes the preprocessing of two wide-band and narrow-band signals in time-sharing mode. The wide-band bandwidth is 60MHz and the sampling rate is 102.4MSPS; the narrow-band bandwidth is 100KHz and the sampling rate is 204.8KSPS. The reconnaissance channel completes the preprocessing of one wide-band signal and the preprocessing of two narrow-band signals within the wide-band bandwidth. The block diagram of the internal implementation of the FPGA is shown in FIG. Fig.13 shown.

[0060] The power amplifier module is composed of a pre-amplifier, a driver amplifier, a final balanced amplifier and a directional coupler connected in sequence. Fig.14 The directional coupler is connected to the output end of the power amplifier to detect the forward and reverse power of the output end of the power amplifier, so as to protect the standing wave ratio of the power amplifier module. The power amplifier module is bidirectionally connected to the signal processing unit through the interface unit, and the signal processing unit monitors the temperature, current, forward power and directional power of the power amplifier module.

[0061] The airborne device may be provided with a positioning module for determining its own position and informing the command center. To achieve data connectivity with the command center or the control center, the airborne device needs to be connected to the command center or the control center network (wireless or wired).

[0062] In terms of structural design, the reconnaissance and excitation integrated machine adopts a modular design, and the channel unit, the data acquisition unit, the signal processing unit, and the interface unit are arranged on mutually independent circuit boards, such as Fig.15 As shown.
