Analysis of a Signal Starting Time Estimator Based on the Page Test Statistic
Abstract
In the detection, localization, and classification of targets in anti-submarine warfare using active sonar, the presence of a target echo must first be detected in the received array data. From the information obtained by the detection, the target is marginally localized in range by the time of detection and in bearing by implementing detectors on multiple beams that selectively accept energy from specific directions. The target echo must then be segmented in the received array data prior to refining the initial bearing and range estimates, depth estimation, or target classification. This requires estimation of the start and stop time of the target echo, a particularly difficult problem when the effect on the transmitted signal due to propagation through the ocean medium and reflection off the target are unknown prior to localization and classification.
