Multi-function radar (MFR) work modes recognition is an important research component of the electronic reconnaissance field. When facing MFR systems equipped with complex mode-waveform mapping relationships and flexible beam scanning techniques, intercepted mode pulse sequences have a wide temporal range feature distributions variable durations, which bring significant challenges for accurate recognition. To address this issue, study constructs novel hierarchical signal model waveform...
When radar receivers adopt digital channelization, it is prone to generating a cross-channel split signal, the rabbit ear effect, and transition band repeated leading errors in signal sorting or identification. The pulse-splitting model detection method proposed this paper can pulses identify them pulse streams, facilitating merging of enhance identification performance. Firstly, mechanism splitting generation deeply analyzed, site theory proposed. Then, number statistical based on geometric...
