Since how to extract the ship wakes＇ optical signal feature and realize the real time monitoring of its strength change is an important base task for the ship optics-wakes elimination technology now, this task designed a monitoring system for the ship＇s optics-wakes. Its design idea, system formation and function, and its relationship with C3I were introduced, a simulation experiment system of the ship optics-wakes monitoring was developed, this system was used to take a primary simulation experiment at sea, and at last the work of digital processing of wake images was completed based on some image processing methods, at the same time the dimensionless values were used to characterize the ship wakes＇ optical signal intensity. The result indicates that system＇s feasibility and validity in monitoring the ship wakes＇ optical signal feature. Compared with traditional measures of monitoring the ship wakes, this system has its strongpoint that it can collect and dispose the data simply, quickly and timely and can supply more quick and reliable assistant decision-making information for commanders to defense the guided torpedo based on the ship optics-wakes.
