The delay/Doppler radar altimeter
IEEE Transactions on Geoscience and Remote Sensing, 1998The key innovation in the delay/Doppler radar altimeter is delay compensation, analogous to range curvature correction in a burst-mode synthetic aperture radar (SAR). Following delay compensation, height estimates are sorted by Doppler frequency, and integrated in parallel. More equivalent looks are accumulated than in a conventional altimeter.

Doppler sensitivity of MIMO radar waveforms
IEEE Transactions on Aerospace and Electronic Systems, 2016Doppler 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, 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 ...

Microwave Doppler Radar Experiment on a River
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Methods 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), 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.

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, 2002It 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.
