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.

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 ...

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.

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.

Doppler Radar Measurements of Turbulence
2016A first-principle analysis of Doppler radar measurements of turbulence is presented. A set of limited, though practical, conditions are assumed to make the problem more tractable, with the primary condition being the discrete and finite temporal sampling of the radar signals.

A new type of pulse doppler radar has been described, which depends on three pulses transmitted in sequence at three different mutually coherent frequencies. The cancellation of stationary targets and signal processing for extraction of moving targets is by mutual comparison of the echo pulses.

Delay-Doppler Radar Imaging [PDF]
, 1986 Abstract : The goal of this project is to formulate and investigate new approaches for forming images of radar targets from spotlight-mode, delay-doppler measurements. These measurements could be acquired with a high-resolution radar-imaging system operating with an optical- or radio-frequency carrier. Two approaches are under study.
