This paper proposes a filter for joint detection and tracking of a single target using measurements from multiple sensors under the presence of detection uncertainty and clutter. To capture the target presence/absence in the surveillance region as well as its kinematic state, we represent the target state as a set that can take on either the empty set or a singleton. The uncertainty in such a set...
MIMO (Multiple Input Multiple Output) concept has been explored for radar/sonar application recently for improving target detection and estimation performance. The existing work in this direction mainly investigates the spatial diversity and waveform designs based on the assumption of the same carrier frequency for multiple transmitters. In this work, we investigate the frequency diversity by using...
In this paper, we introduce a target Bearing and Heading Tracking algorithm (BHT) using bearing-only measurement from a stationary sonar sensor. Since the target location is impossible to be obtained from a single stationary bearing-only sensor, the optimal output of this sensor is the quality bearing tracks. The conventional Bearing-Only Tracker (BOT) using an Extended Kalman Filter (EKF) does not...
Harbor and port protection has become more important in recent years due to the increasing terrorist threats. A surveillance sonar system plays an important role as part of the overall protection system. In this paper, we will discuss a target localization technique by using multiple fixed passive linear hydrophone arrays. Linear array has a better resolution than circular and nonlinear array, but...
