Performance Prediction of FDA-MIMO Radar Detector

2020 IEEE Radar Conference (RadarConf20), 2020
Due 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 ...

Adaptive Monopulse Based Estimation in FDA-MIMO radar

2021 CIE International Conference on Radar (Radar), 2021
This paper deals with the problem of angle and incremental range estimation for a frequency diverse array multiple-input multiple-output (FDA-MIMO) radar using a single data snapshot. To tackle the formulated maximum likelihood estimation problem, an adaptive monopulse procedure (AMP) based method, employing real slope/bias corrections, is designed. At

Adaptive Target Detection With Polarimetric FDA-MIMO Radar

IEEE Transactions on Aerospace and Electronic Systems, 2023
The 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 ...

Design of adaptive detectors for FDA-MIMO radar

2020 IEEE 11th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2020
Adaptive target detection in the presence of Gaussian interference considering a frequency diverse array multipleinput multiple-output (FDA-MIMO) radar is investigated. At the design stage, adaptive detectors are devised according to the generalized likelihood ratio test (GLRT) criterion, where the target range is assumed unknown within the radar cell.

Mainlobe Deceptive Jammer Suppression with FDA-MIMO Radar

2018 IEEE 10th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2018
Anti-jamming technique has become an increasing demand in radar systems due to the fast development of electronic countermeasures. To alleviate the extremely difficult deceptive jammer suppression problem, frequency diverse array (FDA) based multiple-input multiple-output (MIMO) radar is devised and a sample selection based deceptive jammer suppression

FDA-MIMO radar covariance matrix estimation via shrinkage processing

Digital Signal Processing, 2021
Abstract Frequency diverse array multiple-input multiple-output (FDA-MIMO) produces an angle-range-dependent and time-varying transmit beampattern due to the small frequency increment across its array elements, which provides potential applications in new radar techniques.

Range-angle dependent detection for FDA-MIMO radar

2016 CIE International Conference on Radar (RADAR), 2016
In 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 ...
