The Virtual Periscope
Abstract
LONG TERM GOALS. To see surface ships or obstacles, a submarine must rise close to the surface and expose a periscope. This sacrifices the submarine s inherent stealth, limits its submerged speed, and raises the risk of collision. The long-term goal of the Virtual Periscope investigation is to develop the technology that enables submarines to detect surface ships and obstacles from tactically useful depths and ranges. OBJECTIVES The scientific objectives of this investigation were far-reaching and included (a) Advance the through-surface viewing algorithm to demonstrate detection in simulated data of targets subtending between 2 and 3 degrees in elevation; (b) Make the algorithm ready for at-sea demonstration in the form of postprocessing underwater imagery and meta data, performing the necessary motion compensation, wave estimation, and likelihood detection for useful through-surface performance; (c) Design, build, and pool-test the data acquisition system to be used on a seagoing platform; (d) Install the data acquisition system on a submarine, conduct data collection at sea, and perform post-processing to demonstrate useful through-surface imaging.
