Abstract:

This memorandum describes the performance of the passive mode of PAIR system obtained by simulation techniques. Throughout this memorandum this system will be referred to as PADLOC. Detection ranges for in-layer and below-layer targets are predicted using a standard, snorkeling, cavitating, 10 knot Diesel target signature and a 15 knot noncavitating target signature. The passive performance of the ANSQS-23 is included for comparison. These results reported in this memorandum deal with a deep water, 100 ft layer environment for a particular gradient structure.
