Research abstract
A SHALLOW WATER SONAR SYSTEM WILL BE DESIGNED AND ANALYZED USING A UNIQUE RAY-BASED SHALLOW WATER PROPAGATION AND REVERBERATION MODEL. THE BASELINE CANDIDATE SYSTEM IS A PLANAR ARRAY SONAR IN A VDS CONFIGURATION. THE ARRAY USES LIGHTWEIGHT CYLINDRICAL TRANSMITTING ELEMENTS AND DIFAR RECEIVING ELEMENTS TO ACHIEVE EXCELLENT PERFORMANCE IN A COMPACT CONFIGURATION. ITS SIZE AND WEIGHT ARE APPROPRIATE FOR DEPLOYMENT FROM SMALL SHIPS. THE BASELINE SYSTEM WILL BE EVALUATED IN A NUMBER OF SELECTED SHALLOW WATER ENVIRONMENTS RANGING FROM 240 TO 6000 FEET. THE ARRAY BEAM PATTERN WILL BE OPTIMIZED TO EXPLOIT SPATIAL NOISE ANISOTROPIES ASSOCIATED WITH THE HIGHER LOSS ENVIRONMENTS, THEREBY RELIABLY ACHIEVING TARGET DETECTION RANGES OF AT LEAST 15 KILOYARDS.
