Optimum passive bearing estimation
WebActive sensors, for example, give a good estimate of range, while passive sensors are most efficient at estimating the bearing and radiated spectrum of a contact. If it is assumed that prior information about the state of a contact has been collected in a data fusion framework, either by active sonar state estimates or by previous passive ...

Signal and noise are stationary Gaussian processes with arbitrary power spectra, and the noise is assumed to be statistically independent from hydrophone to hydrophone. WebOptimum bearing and range estimators are presented for the planar problem and related to the optimum time delay vector estimator. Keywords Acoustic Source Time Delay …
WebOptimum signal processing for passive sonar target range and bearing estimation is discussed for the case where the sonar array consists of an M‐element linear array of … WebThe number of signals present is assumed to be finite, and each signal is parameterized by a finite number of parameters. Based on measurements of the array output, the objective is to estimate the signals and their parameters. This research area has attracted considerable interest for several years.
