Weighted SPICE Algorithms for Range-Doppler Imaging Using One-Bit Automotive Radar
Xiaolei Shang, Jian Li, Petre Stoica
We consider the problem of range-Doppler imaging using one-bit automotive LFMCW1 or PMCW radar that utilizes one-bit ADC sampling with time-varying thresholds at the receiver. The…
RFI Mitigation for One-bit UWB Radar Systems
Tianyi Zhang, Jiaying Ren, Jian Li +2
Radio frequency interference (RFI) mitigation is critical to the proper operation of ultra-wideband (UWB) radar systems since RFI can severely degrade the radar imaging capability…
Sinusoidal Parameter Estimation from Signed Measurements via Majorization-Minimization Based RELAX
Jiaying Ren, Tianyi Zhang, Jian Li +1
We consider the problem of sinusoidal parameter estimation using signed observations obtained via one-bit sampling with fixed as well as time-varying thresholds. In a previous pape…
Joint RFI Mitigation and Radar Echo Recovery for One-Bit UWB Radar
Tianyi Zhang, Jiaying Ren, Jian Li +2
Radio frequency interference (RFI) mitigation and radar echo recovery are critically important for the proper functioning of ultra-wideband (UWB) radar systems using one-bit sampli…
One-Bit Radar Processing with Time-Varying Sampling Thresholds
Aria Ameri, Arindam Bose, Jian Li +1
Target parameter estimation in active sensing, and particularly radar signal processing, is a long-standing problem that has been studied extensively. In this paper, we propose a n…
Automatic Target Recognition Using Discrimination Based on Optimal Transport
Ali Sadeghian, Deoksu Lim, Johan Karlsson +1
The use of distances based on optimal transportation has recently shown promise for discrimination of power spectra. In particular, spectral estimation methods based on l1 regulari…
Iterative Sparse Asymptotic Minimum Variance Based Approaches for Array Processing
Habti Abeida, Qilin Zhang, Jian Li +1
This paper presents a series of user parameter-free iterative Sparse Asymptotic Minimum Variance (SAMV) approaches for array processing applications based on the asymptotically min…
Sparse Methods for Direction-of-Arrival Estimation
Zai Yang, Jian Li, Petre Stoica +1
Direction-of-arrival (DOA) estimation refers to the process of retrieving the direction information of several electromagnetic waves/sources from the outputs of a number of receivi…
Weighted SPICE: A Unifying Approach for Hyperparameter-Free Sparse Estimation
Petre Stoica, Dave Zachariah, Jian Li
In this paper we present the SPICE approach for sparse parameter estimation in a framework that unifies it with other hyperparameter-free methods, namely LIKES, SLIM and IAA. Speci…
