Abstract

This correspondence derives the Cramer-Rao lower bound (CRLB) for towed array shape estimation when using the receiver outputs in the presence of a single planewave narrowband source and additive white noise. Both known and unknown source directions are considered. The CRLB shows that accurate array shape estimation is possible only if the array shape is relatively linear and the source direction away from endfire.
