A new ambient noise imaging system for ANI, passive and bistatic active acoustic imaging in shallow water
Abstract
Shallow water active and passive sonars can be usefully complimented by broadband Ambient Noise Imaging (ANI) systems. The first AN1 system was largely analogue, produced good images at 38 m range, but was bulky and permitted only a limited range of slgnal processing options. A 24 Gflop 20-120 kHz second-generation phased-array system, ROMANIS, is being built in Singapore. The ROMANIS design is descr~bedd, eta~l~nthge substantial performance improvements and novel processing that it exploits
