2010 IEEE Radar Conference, 2010
For the first time ever, this paper presents the design and implementation of a next-generation of tracking radar systems: the cognitive tracking radar (CTR). At the heart of the CTR, we have a cognitive waveform-selection (CWS) algorithm that can optimally pick the transmit waveform from a prescribed library, in response to information fed back from ...

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 ...

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

Multireceiver passive radar tracking
IEEE Aerospace and Electronic Systems Magazine, 2012In this article, we have proved that using several passive radar receivers is of high interest to improve tracking capacities, by increasing the number of bistatic geometries available and diversifying the target aspect angles (multistatism). The experimental results showed that the multireceiver configuration enables us to initialize a track when the ...

SPIE Proceedings, 1989
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.
