dc.description.abstract	A passive ranging technique which uses SNAP, the SACLANT Centre's normal-mode model, is studied. An examination is made of the sensitivity of the technique to errors in the assumed sound
dc.description.abstract	velocity profile and tilting of a 16 lambda vertical receiving array. Also, the effect of both white and
dc.description.abstract	coloured noise is investigated. Results indicate that for the scenario considered (summer profile in the Mediterranean with a water depth of 130 m and source ranges of 10 and 25 km), the method can be quite robust to sound velocity profile errors on the order of several m/s and array tilts on the order of 1.5 deg . Solutions were obtained with input signal-to-noise ratios as low as -13 dB.
