Defect Detection by MIMO Wireless Sensing based on Weighted Low-Rank plus Sparse Recovery
Udaya S. K. P. Miriya Thanthrige, Ali Kariminezhad, Peter Jung +1
We present a compressive sensing based defect detection by multiple input multiple output (MIMO) wireless radar. Here, defects are inside a layered material structure, therefore, d…
Deep Learning for DOA Estimation in MIMO Radar Systems via Emulation of Large Antenna Arrays
Aya Mostafa Ahmed, Udaya Sampath K. P. Miriya Thanthrige, Aly El Gamal +1
We present a MUSIC-based Direction of Arrival (DOA) estimation strategy using small antenna arrays, via employing deep learning for reconstructing the signals of a virtual large an…
Characterization of Dielectric Materials by Sparse Signal Processing with Iterative Dictionary Updates
Udaya S. K. P. Miriya Thanthrige, Jan Barowski, Ilona Rolfes +3
Estimating parameters and properties of various materials without causing damage to the material under test (MUT) is important in many applications. Thus, in this letter, we addres…
Deep Autoencoders for DOA Estimation of Coherent Sources using Imperfect Antenna Array
Aya Mostafa Ahmed, Omar Eissa, Aydin Sezgin
In this paper a robust algorithm for DOA estimation of coherent sources in presence of antenna array imperfections is presented. We exploit the current advances of deep learning to…
A Reinforcement Learning based approach for Multi-target Detection in Massive MIMO radar
Aya Mostafa Ahmed, Alaa Alameer Ahmad, Stefano Fortunati +3
This paper considers the problem of multi-target detection for massive multiple input multiple output (MMIMO) cognitive radar (CR). The concept of CR is based on the perception-act…
Impact of Spatial Correlation in MIMO Radar
Aya Mostafa Ahmed, Aydin Sezgin, Eduard A. Jorswieck
The impact of spatial correlation on mutual information (MI) is analyzed for MIMO radar. Unlike the work done in literature for statistical MIMO radar, we consider the spatial corr…
