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
