Radar Modulation Recognition of Intra-pulse Overlapping Signals

Existing work on radar modulation recognition iswidely based on the assumption of a single in-pulse signal,whereas overlapping two pulse signals is an actual situation. Thispaper introduces a challenging problem: modulation recognitionof overlapping intra-pulse signals, where the difficulty lies inthe fact that the number of samples grows stepwise with thepermutation of the sub-signals. In this paper, for the first time,a series of methods for target detection are used to solve thisproblem well. Specifically, the authors construct a time-frequencydataset of overlapping signals and train the model’s abilityto extract TFmeta on a single signal.
