Abstract
In this paper, the concept of acoustic Dopplergram is introduced for active detection and tracking of an underwater vehicle from fixed platforms. Past experimental data collected at sea are used to illustrate the Dopplergram and determine the Doppler resolution as well as range resolution in target tracking. As an application, the Dopplergram will be used to detect a fast moving underwater intruder in a harbor environment for ship protection.
