Transmit Beampattern Synthesis for Active RIS-Aided MIMO Radar via Waveform and Beamforming Optimization
Shengyao Chen, Minghui He, Longyao Ran +4
In conventional colocated multiple-input multiple-output (MIMO) radars, practical waveform constraints including peak-to-average power ratio, constant or bounded modulus lead to a…
Reconfigurable Intelligent Surface-Enabled Array Radar for Interference Mitigation
Shengyao Chen, Qi Feng, Longyao Ran +2
Conventional active array radars often jointly design the transmit and receive beamforming for effectively suppressing interferences. To further promote the interference suppressio…
TransMUSIC: A Transformer-Aided Subspace Method for DOA Estimation with Low-Resolution ADCs
Junkai Ji, Wei Mao, Feng Xi +1
Direction of arrival (DOA) estimation employing low-resolution analog-to-digital convertors (ADCs) has emerged as a challenging and intriguing problem, particularly with the rise i…
LiQuiD-MIMO Radar: Distributed MIMO Radar with Low-Bit Quantization
Yikun Xiang, Feng Xi, Shengyao Chen
Distributed MIMO radar is known to achieve superior sensing performance by employing widely separated antennas. However, it is challenging to implement a low-complexity distributed…
On the Mutual Interference between Spaceborne SARs: Modeling, Characterization, and Mitigation
Huizhang Yang, Mingliang Tao, Shengyao Chen +2
Since by the International Telecommunications Union (ITU) regulatory the radio spectrum available to spaceborne synthetic aperture radar (SAR) is restricted to certain limited freq…
BiLiMO: Bit-Limited MIMO Radar via Task-Based Quantization
Feng Xi, Nir Shlezinger, Yonina C. Eldar
Recent years have witnessed growing interest in reduced cost radar systems operating with low power. Multiple-input multiple-output (MIMO) radar technology is known to achieve high…
Non-Common Band SAR Interferometry via Compressive Sensing
Huizhang Yang, Chengzhi Chen, Shengyao Chen +2
To avoid decorrelation, conventional synthetic aperture radar interferometry (InSAR) requires that interferometric images should have a common spectral band and the same resolution…
Gridless Parameter Estimation for One-Bit MIMO Radar with Time-Varying Thresholds
Feng Xi, Yijian Xiang, Shengyao Chen +1
We investigate the one-bit MIMO (1b-MIMO) radar that performs one-bit sampling with a time-varying threshold in the temporal domain and employs compressive sensing in the spatial a…
