Storm tracking in Doppler radar images
Proceedings of 1st International Conference on Image Processing, 2002An automated tracking algorithm for Doppler radar storms is presented. Potential storms in Doppler radar images are hypothesized as regions of high water density (high intensity in the radar images) using a merge-and-split region growing algorithm. Potential storms are verified by a relaxation labelling scheme that attempts to finds the best tracks ...

Radar Tracking of Low-Altitude Targets
IEEE Transactions on Aerospace and Electronic Systems, 1974The antenna elevation control signal and the associated staticequilibrium equations are analyzed for the case of tracking of lowaltitude targets for both monopulse and conical-scanning radar. Three possible equilibrium positions of the radar antenna under static operating conditions are ascertained.

Accuracy of fused track for radar systems
Signal Processing, 2005This paper provides some new results on track fusion for radars. In particular, it provides a relationship between the accuracies of fused tracks for co-located and non co-located radar sensors. The uncertainty volume corresponding to the fused estimate is smaller than the volume of the intersection of the uncertainty ellipsoids associated to the ...

Bell System Technical Journal, 1961
This paper is concerned with the radar employed at Bell Telephone Laboratories, Holmdel, New Jersey, site for tracking the Echo I satellite. The radar was originally designed for the sole purpose of antenna pointing. Recently, however, it has also been employed to measure earth-balloon-earth path loss at regular intervals of time in order to keep track

Track-to-track fusion schemes for a radar network
IET International Conference on Radar Systems (Radar 2012), 2012Radar networks require techniques for information fusion, such as track-to-track fusion. However, existing fusion schemes in the literature seldom apply radar-like models, which can have profound effects on performance. Hence, this paper describes and analyses state of the art algorithms for track-to-track fusion assuming range-Doppler radar ...

Automated tracking of filmed radar echoes
Pattern Recognition, 1981Abstract The paper describes a general methodology for tracking fuzzy planar objects. It involves a five-stage tracking cycle with an internal fuzzy object locator sub-cycle. The methodology is illustrated by an application to tracking radar echoes of shipping in the English Channel on 16 mm film.

Track Initiation for Maritime Radar Tracking with and without Prior Information
2018 21st International Conference on Information Fusion (FUSION), 2018Reliable track initiation is an important component of a tracking system, especially when it is used as part of a more general collision avoidance (COLAV) system. Some tracking methods (e.g., IPDA) come with an in-built track initiation capability, while other methods (e.g., JPDA) lack this capability, which in such cases typically is taken care of by ...

Inverse probability in angular-tracking radars
IEEE Transactions on Information Theory, 1956An angular-tracking radar of the pulsed type is analyzed for targets whose signal-return in the video follows a Rayleigh distribution. The pulse amplitudes are assumed independent from pulse-to-pulse but closely correlated for the duration of a pulse width. White Gaussian noise is introduced into the input of the receiver.
