Kalman filter algorithms for a multi-sensor system
D. Willner,C. Chang,K. Dunn +2 more
TL;DR: The purpose of this paper is to examine several Kalman filter algorithms that can be used for state estimation with a multiple sensor system and the data compression method is shown to be computationally most efficient.
Journal ArticleDOI
Ballistic trajectory estimation with angle-only measurements
TL;DR: In this paper, an iterative least square estimation algorithm is applied to the problem of state estimation of ballistic trajectories with angle-only measurements, and a filter initiation procedure is suggested.
Proceedings ArticleDOI
Measurement correlation for multiple sensor tracking in a dense target environment
TL;DR: In this article, the authors describe an algorithm for correlating measurements from several sensors in a dense target environment and show that the correlation problem is similar to the assignment problem in operation research with assisgnment penalties being equal to the sufficient statistic of the generalized likelihood ratio test.
Journal ArticleDOI
On GLR detection and estimation of unexpected inputs in linear discrete systems
TL;DR: The application of linear filtering techniques is demonstrated to obtain a recursive GLR algorithm so that the requirement for matrix inversions in the previously known GLR algorithms can be reduced or avoided.
ReportDOI
Kalman filter configurations for multiple radar systems
TL;DR: Several Kalman filter algorithms that can be used for state estimation with a multiple sensor system are examined and their results are compared with a suboptimum tracking algorithm which processes only multiple range measurements.
