Abstract:

Matched-field processing results are presented which compare the resolution (in range, depth, and azimuth) and peak-to-sidelobe ratios obtained using a bottom-mounted horizontal line array and a tilted vertical line array. The arrays were deployed in the May 1996 shallow water evaluation cell experiment (SWellEx-96) carried out west of Point Loma in 200-m water of complex bathymetry. Results are presented for a towed source transmitting signals between 49 and 388 Hz at ranges between 0.7 and 6 km and at bearings between broadside and endfire.
