For the above-mentioned reconnaissance training module and interference training module, the working principles of the reconnaissance training module and interference training module are described by taking reconnaissance and interference of Link11 data chain signals as an example.
Since the Link11 data chain has a very fixed format, the signal characteristics of the quadriphase shift keying modulated signal are very obvious for the tones of 15 sub-carrier frequencies, and the FFT spectrum analysis technique can be adopted to determine whether the signal is the communication signal of the Link11 data Link by accurately measuring the 15 sub-carrier frequencies and displaying the spectrum and the measurement result.
The Link11 communication signal is subjected to spectrum analysis by adopting a digital signal processor DSP, the digital signal processor DSP is a core component of a search receiver and an analysis receiver, and the search receiver and the analysis receiver both have the capability of reconnaissance on the Link11 communication signal.

In order to achieve the best interference effect, a proper interference pattern and interference frequency offset need to be selected. Since Link11 data communication requires a high signal-to-noise ratio and its signal bandwidth is relatively fixed, it is suppressed by using frequency modulation noise. When the reconnaissance equipment finds the Link11 data signal, the interference exciter is automatically controlled by the comprehensive display and control console, the interference pattern is set as frequency modulation noise, the corresponding interference bandwidth (bandwidth 3k) is set, the interference response is rapidly made, the best interference effect can be achieved, and the Doppler sound and the synchronous sound of the Link11 single tone and the Link11 double tone can be selected to interfere.
