Paper Abstract

Relatively inexpensive laser-guided weapons were identified as an important threat to naval platforms operating in littoral environments. Countermeasures (CM) developed against laser-assisted threats in air and land environments are all based on accurate threat detection. Due to the limited performance of current laser detecting capabilities applied to large maritime platforms, there are no known CMs that can be used to protect them. We present a new far off-axis laser detection approach for minimizing the number of laser sensors required to protect a ship. A model predicting the detection of aerosol scattering in the spectral band used by laser threats, exploiting the high humidity conditions present in maritime environments, is described, as well as its limitations and some preliminary results regarding its validation.
