Shipboard Laser Detection

Sensing Strategies, Inc. (SSI) has extensive expertise in laser detection, which allows us to propose an ambitious effort with a combined analytical and experimental approach. Our proposal includes irradiance and sensor performance predictions to estimate the threat detection envelopes for a sample sensor concept. With these predictions as a basis going into the effort, the Phase I resources can be focused on technology tradeoff and system miniaturization and design issues. Objectives of this Phase I proposed effort are: (1) Develop a shipboard laser warning sensor preliminary design that achieves comparable or improved performance over SBLAS in the 1.06 micron region while reducing the size of the off-axis and direct illumination systems, and (2) Propose an off-axis collection system for laser threat detection in the 1.5 micron range and predict its expected performance in tactical scenarios. The objective of the optional field test component is to collect quantitative aerosol scatter irradiance data to verify the model predictions and characterize sensitivity of SBLAS and a breadboard SSI receiver. The primary product from the Phase I effort will be a development plan for a Phase II prototype sensor system based on the miniaturized designs developed under Phase I.
