Embodiment Construction
[0038] The present invention is described in further detail now in conjunction with accompanying drawing.
[0039] Such as figure 1 As shown, this embodiment includes the following steps:
[0040] Step 1: For 6 typical interference types: monotone continuous wave interference, broadband comb spectrum interference, chirp interference, pulse interference, narrowband random binary code modulation interference and wideband random binary code modulation interference, extract these interferences respectively There are 6 types of signal energy limit factor, 3dB bandwidth of normalized spectrum, normalized spectrum kurtosis coefficient, standard deviation of normalized spectrum impulse part, time domain peak-to-average ratio and fractional Fourier domain energy concentration difference Characteristic Parameters. By extracting entities, attributes, and attribute values, and according to the triple organization form of "entity-attribute-attribute value", the knowledge map of the inter...
