Abstract:

The problem of designing optimum signals and receivers for an active sonar system in a reverberation limited environment is studied. A suitable model of the reverberation return is developed. The return is characterized as a zero-mean non-stationary Gaussian random process with a correlation function which is assumed to be known. The structure and resultant performance of the optimum and conventional receivers are derived. Some general signal properties useful in signal design are derived. Two cases are considered in detail reverberation which is homogeneous in range and results in interference which is a stationary Gaussian process, and reverberation which is nonhomogeneous in range and results in a non-stationary Gaussian process.
