Canada’s Operational Doppler Radar [PDF]
, 1990 The King Weather Radar Research Station of the Atmospheric Environment Service (AES), located north of the metropolitan Toronto area in Southern Ontario, is a component of the Canadian weather service radar network. The only Doppler weather radar in the country, it was instituted as part of the research program of the Cloud Physics Division of AES and ...

The Doppler Radar Signals Processing
2019 9th International Conference on Advanced Computer Information Technologies (ACIT), 2019A spectral method for processing Doppler radar signals is proposed. Discrete fast Fourier transform is commonly used in communications (areas) in both mobile phone processes and devices for compressing audio and video to transmit via telecommunications networks. For now the relevant objective is to increase the efficiency of these systems.

A Doppler radar for multiple targets
IEEE Transactions on Instrumentation and Measurement, 1994A programmable instrument for the simultaneous measurement of velocities and acceleration or deceleration of different objects becomes possible through the use of spectral analysis of the Doppler signal. Programmable gain and frequency synthesis is under software control.

Publisher Summary This chapter throws light on the pulse Doppler radar. Doppler shifts are a key part of the detection and tracking of objects. For this reason, nearly all radar systems incorporate Doppler processing. It has been working since the ground returns are at the same range as the vehicle, the difference in velocity is the means of ...

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 ...

Doppler Radar with Polarization Diversity
Journal of the Atmospheric Sciences, 1973Abstract In this note we propose a technique to uncouple the tie between unambiguous Doppler velocity and range. Transmission of orthogonally polarized waves in pairs of pulses increases a weather Doppler radar's capability to unambiguously resolve velocity spectrum mean and variance at simultaneous range locations sampled in real time.

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,

Doppler Radar Observations of Mammatus
Monthly Weather Review, 1995Abstract Observations of mammatus-like cloud features associated with a convective rain shower were obtained using a vertically pointing 8-mm-wavelength Doppler radar. The radar's excellent sensitivity and resolution allowed even very weak, finescale features of the cloud to be resolved.
