Doppler sensitivity of MIMO radar waveforms

IEEE Transactions on Aerospace and Electronic Systems, 2016
Doppler sensitivity of multiple-input multiple-output (MIMO) radar waveforms is complicated but rarely is of concern in most existing MIMO waveform designs. For both distributed and colocated MIMO radar, this paper studies the impact of Doppler sensitivity on both autocorrelation and mutual correlation sidelobes of both constant-modulus MIMO transmit ...

A processor for pulse-doppler radar

IEEE Transactions on Electron Devices, 1976
Methods 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 ...

Microwave Doppler Radar Experiment on a River

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Methods for measuring of sea currents are currently being actively developed. Significant success has been achieved at the middle incidence angles, when the scattering mechanism is presumed to be resonant. This paper presents results from experiments with Doppler radar installed on the bridge over a river.

The Doppler Radar Signals Processing

2019 9th International Conference on Advanced Computer Information Technologies (ACIT), 2019
A 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.

Doppler weather radar

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 ...

Estimation Of Range-doppler Radar Images

1993 IEEE International Symposium on Circuits and Systems, 2002
It is shown that most accurate reconstruction of a range-Doppler target density that can be computed from N waveforms and their echoes is obtained by transmitting the singular functions corresponding to the N largest singular values of two kernels derived from the target density.

Doppler Radar Clutter

IEEE Transactions on Aerospace and Navigational Electronics, 1964
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.

Quantification of choreatic movements by Doppler radar

Acta Neurologica Scandinavica, 2009
A simple and effective method is described to quantify involuntary movements. The method is based on the Doppler radar principle. Reproducibility of the method is demonstrated in a group of patients with Huntington's chorea and Tardive Dyskinesia.

Doppler radar sensor for occupancy monitoring

2013 IEEE Radio and Wireless Symposium, 2013
This 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.
