Claim 11:
12. The communication anti-interference detection device according to claim 9, wherein the interference detection module comprises:
an interference detection circuit, the interference detection circuit comprising an inverse Fourier transformer, a memory, a phase inverter and a convolutor;
the inverse Fourier transformer is configured to process the demodulated signal to acquire the first signal;
the memory is configured to store the preset baseband signal;
the phase inverter is configured to invert the phase of the preset baseband signal to acquire the second signal; and
the convolutor is configured to convolve the first signal and the second signal to remove a useful sine wave signal, so as to acquire the detection signal.
