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.

Range-Doppler radar sensor fusion for fall detection
International Radar Conference, 2017Falls are the major cause of accidents in the elderly population. Propelled by their non-intrusive sensing capabilities and robustness to heat and lighting conditions, radar-based automated fall detection systems have emerged as a candidate technology ...

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.

International Conference on Systems for Energy-Efficient Built Environments, 2017
This study evaluates the sensitivity of our novel and non-intrusive approach, powered by Doppler radar sensors to assess thermoregulation states as feedback to heating, ventilation, and air-conditioning (HVAC) systems. Thermoregulation-based HVAC control

International Journal of Electronics, 1969
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.

A security Doppler radar experiment
2016 IEEE Radar Methods and Systems Workshop (RMSW), 2016The paper presents an indoor experimental study of the “NORMA” security Doppler radar's information signal, with a human target moving across and along the detector's radiation direction.

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.

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.
