Intrapulse modulation recognition based on pulse description words

摘要

The intrapulse modulation recognition of radar signals is an important part of the radar reconnaissance. By means of the digital channelized receiver on processing simultaneous signals, the recognition method in this paper accomplishes the separation and recognition of the different modulated signals from a complex multiple environment with simultaneous signals. Further, from the statistical characteristics of the intrapulse instantaneous frequency, the modulation types can be recognized and the modulation parameters can be extracted using this method. The experimental result provided the effectiveness of this proposed method.
