Adaptive Target Detection With Polarimetric FDA-MIMO Radar
IEEE Transactions on Aerospace and Electronic Systems, 2023The problem of adaptive radar detection with a polarimetric frequency diverse array multiple-input multiple-output radar is addressed in this article. At the design stage, the target detection problem is formulated as a composite hypothesis test, with the unknowns given by the target angle, incremental range (target displacement with respect to the ...

DOA estimation and tracking for FDA-MIMO radar signal
Digital Signal Processing, 2020Abstract Direction-of-arrival (DOA) estimation is a fundamental problem in many applications of array signal processing. In practice, it is more important to track the DOAs of moving target signals. In this paper, we study the problem of tracking the DOAs of multiple signals in the frequency diversity array (FDA)-MIMO radar system.

A Reduced-Dimension MUSIC Algorithm for Monostatic FDA-MIMO Radar
IEEE Communications Letters, 2021This letter proposes a one-dimensional multiple signal classification (MUSIC) algorithm for the joint angle and range estimation in monostatic multi-input multi-output (MIMO) radar with frequency diverse array (FDA). The proposed algorithm can reduce the computational complexity greatly compared to the two-dimensional MUSIC (2D-MUSIC) algorithm but ...

Performance Prediction of FDA-MIMO Radar Detector
2020 IEEE Radar Conference (RadarConf20), 2020Due to the complex shape of the target, the radar cross-section (RCS) scintillations of the target will affect the radar detection performance. Therefore, a signal model for frequency diverse array (FDA) multiple-input and multiple-output (MIMO) radar based on the distributed source model is constructed in this paper, which takes advantage of spatial ...

Transceive Beamforming With Accurate Nulling in FDA-MIMO Radar for Imaging
IEEE Transactions on Geoscience and Remote Sensing, 2020Beamforming plays a crucial role in synthetic aperture radar (SAR) for interference mitigation and ambiguity unaliasing. In this article, a series of novel beamforming methods for SAR systems is proposed based on nulling the transceive beampattern accurately in frequency diverse array (FDA)-multiple-input and multiple-output (MIMO) scheme.

Range-angle dependent detection for FDA-MIMO radar
2016 CIE International Conference on Radar (RADAR), 2016In this work, we address the problem of detecting the presence of target signal while rejecting potential deceptive jamming under the multiple-input multiple-output (MIMO) radar with frequency diverse array (FDA) as the transmit array. The problem at hand is solved resorting to the generalized likelihood ratio test (GLRT); at the design stage we ...
