Development of a MIMO Radar System Demonstrator - Calibration and Demonstration of First Results
, 2012 The success of current spaceborne Synthetic Aperture Radar (SAR) is boosting the performance requirements of next generation systems. In order to cope with the evolution of SAR the design of the new systems will need to meet higher requirements for ...

Chaff identification method based on Range‐Doppler imaging feature
IET Radar, Sonar & Navigation, 2022 Chaff is widely used in electronic countermeasures as an effective passive jamming method. This study proposes a chaff identification method that integrates the distribution of distance, Doppler frequency, and power in Range‐Doppler imaging.

Waveform Selection for a Scanning Radar in the Maritime Environment
, 2021 Detection of slow moving targets for a scanning radar in the maritime domain is typically performed using noncoherent detectors with both pulse-to-pulse and/or scan-to-scan integration.

Dual-polarization radar rainfall estimation in Korea according to raindrop shapes obtained by using a 2-D video disdrometer [PDF]
Atmospheric Measurement Techniques, 2016 Polarimetric measurements are sensitive to the sizes, concentrations, orientations, and shapes of raindrops. Thus, rainfall rates calculated from polarimetric radar are influenced by the raindrop shapes and canting.

Convolutional neural networks for radar HRRP target recognition and rejection
EURASIP Journal on Advances in Signal Processing, 2019 Robust and efficient feature extraction is critical for high-resolution range profile (HRRP)-based radar automatic target recognition (RATR). In order to explore the correlation between range cells and extract the structured discriminative features in ...

Highlights of Astronomy, 1998 Radar techniques can be a powerful adjunct for studying meteor storms in general because of their sensitivity, capacity for continuous observations and their use of current techniques facilitating the handling of data. While some radars are limited to only a range-time presentation (and so adequate for a time-profile description of a storm event), some

Information and Inference, 2016 In this paper we study the identification of a time-varying linear system from its response to a known input signal. More specifically, we consider systems whose response to the input signal is given by a weighted superposition of delayed and Doppler shifted versions of the input.
