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 ...

Elderly Fall Detection With Vital Signs Monitoring Using CW Doppler Radar
IEEE Sensors Journal, 2021Falling is the main cause of disability and fatality of elderly. In this work we used a 24 GHz continuous-wave Doppler radar to develop a low price and a highly accurate fall detection system aiming at observing indoor human activities and detecting fall

Dual-Use of OTFS Architecture for Pulse Doppler Radar Processing
International Radar Conference, 2022Orthogonal time frequency space (OTFS) modulation is a recently proposed modulation scheme that places the information symbols to be transmitted over the wireless channel in the delay-Doppler (DD) domain. In this paper, we argue that the OTFS discrete DD

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 ...

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.
