Claim Text:
1. An apparatus for detecting spectrum interference, comprising: a receiving antenna, configured to receive a spatial signal, wherein the spatial signal comprises a normal signal and an interference signal; a normal signal processing unit, configured to perform wave filtering and low-noise amplification for the normal signal received by the receiving antenna, and to send the processed normal signal to a radio frequency channel processing unit; an interference signal processing unit, configured to preprocess the interference signal received by the receiving antenna, and to send the preprocessed interference signal to the radio frequency channel processing unit; the radio frequency channel processing unit, configured to perform radio frequency processing for the received normal signal, and to perform radio frequency processing for the preprocessed interference signal in an idle timeslot; a radio frequency sampling unit, configured to perform, according to an input sampling clock, radio frequency sampling for the normal signal performed the radio frequency processing, to perform radio frequency sampling for the interference signal performed the radio frequency processing in an idle timeslot, and to send the interference signal performed the radio frequency sampling to an interference signal detecting unit; and the interference signal detecting unit, configured to perform fast Fourier transform in a digital domain for the interference signal performed the radio frequency sampling, to perform frequency band identification, and to acquire a communication mode of the interference signal.
