Quantification of choreatic movements by Doppler radar

Acta Neurologica Scandinavica, 2009
A simple and effective method is described to quantify involuntary movements. The method is based on the Doppler radar principle. Reproducibility of the method is demonstrated in a group of patients with Huntington's chorea and Tardive Dyskinesia.

Robust Design of Radar Doppler Filters

IEEE Transactions on Signal Processing, 2016
This paper considers the design of robust filters for radar pulse-Doppler processing when the interference is a wide sense stationary random process. The figure of merit which is optimized is the signal-to-interference-plus-noise ratio (SINR) at the filter output under a multitude of constraints accounting for Doppler filter sidelobes as well as ...

Adaptive algorithms for Doppler weather radar

2005 European Microwave Conference, 2005
New complex adaptive algorithms of detection and measurement of turbulence intensity in weather formations are proposed. Algorithms are based on calculation of spectrum estimations by using the signals reflected from the adjacent range bins. Statistical hypothesis about the difference between the adjacent or next spectra are checked.

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 ...

CHIRP Doppler radar

Proceedings of the IEEE, 1984
The idea of combining the clinical procedure known as Reconstruction Tomography, and the radar processing for linear FM pulse compression, in order to map radar backscatter energy, is explained. A possible configuration is described.

Pulse-Doppler Radar

2004
A Doppler radar is defined by as 'a radar which uses the Doppler effect to determine the radial component of relative radar target velocity or to select targets having particular radial velocities.' A pulse-Doppler (or pulsed-Doppler) (PD) radar is defined as 'a Doppler radar that uses pulsed transmissions.' PD radar is used extensively for detecting ...

Pulse Doppler radars

1993
This chapter deals with Doppler techniques and their different applications for surveillance radar, multifunction radar and synthetic aperture radar. The chapter presents: an analysis of a simple pulse Doppler radar [fixed station, low pulse repetition frequency (PRF), no range ambiguity] (radar characteristics, power and spectra of clutter and target,
