Bearings only target tracking - maneuvering target.
Dimitrios Kourkoulis · Defense Technical Information Center (DTIC) · 1984
The estimation of the position and velocity of a sonar target moving in a two-dimensional frame is studied in this paper. The estimator is a Kalman filter which processes noisy bearings of the target gathered by the tracker. The case of maneuvering targets is examined a solution using a variable value of the system's noise covariance matrix is studied. Simulation programs in FORTRAN are provided for a simple example and for maneuvering and nonmaneuvering bearings-only targets. Originator-supplied keywords: Kalman filter, Passive tracking, Bearings-only tracking, and Extended kalman filter.
