Silence tracking radar

2001 CIE International Conference on Radar Proceedings (Cat No.01TH8559), 2002
A high performance linear FMCW radar sensor and its implementation as tracking radar are presented. The radar has been built with an all-solid state transmitter with 200 mw output power and two channel receivers with 9 dB noise figure. Tracking range of more than 10 km, angle error of better than 0.5 mrad and range error of better than 5 meters have ...

Informative Radar Selection for Tracking in Radar Networks

IET International Radar Conference 2015, 2015
In radar networks, radar selection has played a more and more important role. Many radar selection methods have been proposed. Recently a novel method which is based on sparsity-aware matrix decomposition has been proposed to identify informative sensors for target tracking. However, this method had stringent constraints and was under the assumption of

Monopulse MIMO Radar for Target Tracking

IEEE Transactions on Aerospace and Electronic Systems, 2011
We propose a multiple input multiple output (MIMO) radar system with widely separated antennas that employs monopulse processing at each of the receivers. We use Capon beamforming to generate the two beams required for the monopulse processing. We also propose an algorithm for tracking a moving target using this system.

Radar Tracking of Low-Altitude Targets

IEEE Transactions on Aerospace and Electronic Systems, 1974
The 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.

Storm tracking in Doppler radar images

Proceedings of 1st International Conference on Image Processing, 2002
An 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 ...

Accuracy of fused track for radar systems

Signal Processing, 2005
This 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 ...

Track-to-track fusion schemes for a radar network

IET International Conference on Radar Systems (Radar 2012), 2012
Radar 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 ...

Track Initiation for Maritime Radar Tracking with and without Prior Information

2018 21st International Conference on Information Fusion (FUSION), 2018
Reliable 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 ...

Bayesian tracking in UWB radar sensor networks

2013 IEEE International Conference on Communications Workshops (ICC), 2013
A UWB multistatic radar system, typically composed of one transmitter and several receivers, is a promising solution for tracking an intruder moving within a given surveillance area, because of its extraordinary localization accuracy and very low probability of intercept.
