Abstract

Ultra-short baseline system (USBL) is widely used in ocean observation as a result of small aperture size and ease install. However, the USBL has lower accuracy at a long-range. In order to increase the precision, the estimation algorithm of inserting time-delay in correlation peak is used for passive location four-element-array. Simulation shows that the algorithm can exactly estimate the time-delay difference and increase location precision.
