Fundamental Limits of Adaptive Beamforming Under Finite Training
Zhiyong Cheng, Shengyao Chen, Di Song
Finite training reduces the output signal-to-interference-plus-noise ratio (SINR) of an adaptive beamformer, and a natural question is how much of this loss is unavoidable. This pa…
Space-Time Adaptive Processing Using Random Matrix Theory Under Limited Training Samples
Di Song, Shengyao Chen, Feng Xi +1
Space-time adaptive processing (STAP) is one of the most effective approaches to suppressing ground clutters in airborne radar systems. It basically takes two forms, i.e., full-dim…
Radar Interferometry using Two Images with Different Resolutions
Huizhang Yang, Chengzhi Chen, Shengyao Chen +2
Radar interferometry usually exploits two complex-valued radar images with the same resolution to extract terrain elevation information. This paper considers the interferometry usi…
Quadrature compressive sampling SAR imaging
Huizhang Yang, Shengyao Chen, Feng Xi +1
This paper presents a quadrature compressive sampling (QuadCS) and associated fast imaging scheme for synthetic aperture radar (SAR). Different from other analog-to-information con…
A General and Yet Efficient Scheme for Sub-Nyquist Radar Processing
Shengyao Chen, Feng Xi, Zhong Liu
We study the target parameter estimation for sub-Nyquist pulse-Doppler radar. Several past works have addressed this problem but either have low estimation accuracy for off-grid ta…
Gridless Quadrature Compressive Sampling with Interpolated Array Technique
Feng Xi, Shengyao Chen, Yimin D. Zhang +1
Quadrature compressive sampling (QuadCS) is a sub-Nyquist sampling scheme for acquiring in-phase and quadrature (I/Q) components in radar. In this scheme, the received intermediate…
