Observing littoral waves by Doppler radar
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009The offshore observation of the wavefield with coherent radar systems consist a common practice for the study of the electromagnetic waves probing the sea surface waves and for the extraction of information of the sea waves. In this investigation, a Dopplerized, horizontally polarized, nautical radar is utilized for the monitoring of the wavefield ...

Basic principles of a polarimetric Doppler radar are described in this chapter. These include formation of the transmitted EM wave by a pulsed radar, reception of the radar signal reflected from a single scatterer, and its transformation in the antenna, microwave assembly, and two receivers for orthogonally polarized components of the backscattered EM ...

Robust Design of Radar Doppler Filters
IEEE Transactions on Signal Processing, 2016This 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, 2005New 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, 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 ...

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 ...
