Polarimetric Doppler Radar [PDF]
, 2019 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 ...

Proceedings of the IEEE, 1979
The Doppler weather radar and its signals are examined from elementary considerations to show the origin and development of useful weather echo properties such as signal-to-noise ratio (SNR), range correlation, signal statistics, etc. We present a form of the weather radar equation which explicitly shows the echo power loss due to finite receiver ...

A processor for pulse-doppler radar
IEEE Transactions on Electron Devices, 1976Methods are presented for combining charge-coupled device (CCD) and surface acoustic wave (SAW) techniques to advantage for processing coherent radar signals in order to extract target range and velocity information. Experiments have validated a scheme of combined discrete CCD's to form an analog store with orthogonal input and output sequencing ...

Doppler radar sensor for occupancy monitoring
2013 IEEE Radio and Wireless Symposium, 2013This paper investigates the use of Doppler radar sensor for occupancy monitoring. The feasibility of true presence is explored with Doppler radar occupancy sensors to overcome the limitations of the common occupancy sensors. The common occupancy sensors are more of a motion sensor than a presence detector.

Computation of the entire clutter spectrum for Doppler radar has been reduced to a few simple formulas, by integration of reflected energy between constant Doppler loci, using the fourth power range law. The results are widely applicable, and have been found in agreement with both flight tests and a computer program study.

Vibrating Antenna Doppler Radar
2020 17th European Radar Conference (EuRAD), 2021This paper presents a new method of gaining spatial resolution in continuous wave (CW) Doppler radars by using a vibrating antenna. Resolution of direction finding, though conventionally controlled through beam steering or other circuitry, is decoupled from the antenna and front-end circuitry by vibrating the antenna in a controlled fashion.

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 ...
