A Novel Concept for a Self-Focusing and Target Seeking Sonar System.
Abstract
A new concept for a retrodirective target-seeking sonar system is described. The system is based on time reversal. This is achieved by storing the target return in a serial access memory and reading out the stored information in reverse order for retransmission. The theory of the device is given for noise-free operations and stationary array and targets. The motion sensitivity of the system is discussed and the effect of white noise and reverberation noise on the system considered. A computer simulation of the system in a reverberation environment is described and some results of the simulation given. (Author)
