A NATO STO research team has developed new approaches to detect and identify submarine periscopes from high altitudes, potentially enabling militaries to cover wider areas during intelligence, surveillance and reconnaissance (ISR) maritime operations. 


Detection of submarine periscopes has traditionally been carried out at low altitudes with fast scanning radars. Carrying out ISR missions at higher altitudes would enable operators to cover a wider area, but it also makes it more difficult to distinguish submarine masts from other sea clutter. The ideal solution would therefore combine accurate periscope discrimination with a large coverage area.







The research team, formed under the STO Sensors and Electronics Technology (SET) Panel, also developed a new approach that combines electromagnetic modelling with statistical models to more realistically represent sea clutter. The figure below provides an example, with a mast moving through a modelled sea surface and corresponding radar data displayed in different domains. 


The six-Nation team (SET-271) made important advancements in performance prediction modelling, target and wake detection, maritime track-before-detect, and the use of neural networks and dictionary learning in target discrimination. They also proposed several waveform options for both mechanically scanned and active electronically scanned array (AESA) radars.   



The team’s approach could be used to advance periscope detection and discrimination activities, though it must first be tested using real periscope mast data. The team identified challenges associated with the collection of real-world data, which it hopes will inform future work in this area.
