Multi-function radars (MFRs) work with pulse groups, and pulses in different groups are weakly correlated, which greatly increases the difficulty for MFR deinterleaving, especially cases of significant data noises. At present, no relevant research results have been reported to address this problem. In article, a hierarchical deep learning model will be established describe sequential patterns t...
