Previous work in the theory of laser radar operation has addressed the problems of detection, range and Doppler estimation for multipixel speckle targets. In this paper, the theory of automatic tracking for such targets is developed. A track-while-image approach is adopted in which the laser radar produces a sequence of raster scans, called frames ...

Radar/sonar multitarget tracking
IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259), 2002This paper examines optimal joint detection and tracking of multiple targets that move randomly in spatially uncorrelated and correlated Gaussian and non-Gaussian (heavy tail) clutter. We develop an integrated detector/tracker and illustrate its performance with synthetic data.

An Antichaff Technique for Tracking Radar
European Radar Conference, 2005. EURAD 2005., 2005The critical interference in radar systems is unwanted echo named clutter. Some important clutter includes echoes from land, weather (particularly rain), sea and deliberated chaff. Therefore, a military radar designer is faced with the problem of how to reject interference. In this paper, chaff elimination methods such as Doppler processing and log-FTC

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.

Sensor Radar Networks for Indoor Tracking
IEEE Wireless Communications Letters, 2014Sensor radars (SRs) are important for a variety of applications requiring passive tracking of moving targets. The accuracy of passive tracking is severely degraded by wireless propagation impairments such as multipath, clutter, and non line-of-sight conditions, especially in indoor environments.

The problems of low-angle tracking over the earth's surface are explored in the light of rough-surface scattering theory. A detailed model of diffuse scattering is constructed which agrees with available test data and which permits the power distributions in radar coordinates to be estimated.

Informative Radar Selection for Tracking in Radar Networks
IET International Radar Conference 2015, 2015In 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

IEEE Transactions on Aerospace and Electronic Systems, 1982
The track acquisiton range of a track-while-scan radar is defined as the range at which the cumulative probability of M detections in N scans is 90 percent. Track acquisition ranges for 2 out of 3, 2 out of 4, and 3 out of 4 detection criteria are presented for Swerling 0, 1, and 3 target models.

When radar systems are discussed in the literature or the remainder of this text, it is in the context of a sensor providing observations of the environment. While some of those measurements are responses from coherent waveforms of finite duration, the environment is treated as stationary with at most linear motion on the targets.
