Abstract

This paper derives system performance for a chaotically modulated laser rangefinder operating in turbid water, both as a function of rangefinder parameters and as a function of water and target characteristics. An ocean impulse response simulator is used to calculate signal-to-noise-ratios and target detection performance at a variety of water turbidities and target ranges. The use of a digital filter chain is demonstrated, and its effect on system performance is considered. The use of an optical backscatter-removal filter is proposed, and its potential effect on system performance is considered.
