Controlled Towed Array Surveillance System (CTASS) Array Static Test and Simulation.
Abstract
An evaluation of the Controlled Towed Array Surveillance System (CTASS) was made by using recorded sea noise as received with CTASS sensors, filtering and digitizing the noise data, simulating sinusoidal target signals, and simulating CTASS performance with respect to output ratio, (S/N. It was found that (S/N) decreases as the array size is increased. This disturbing trend prompted an analytical investigation using noise-free conditions, but assuming realistic integration times. That analysis confirmed the trend of decreasing (S/N) with increasing array size. Further CTASS evaluation work was therefore halted, since the presently conceived CTASS configuration cannot be regarded as a viable array processing system. (Author)
