Towards a performance bound on MIMO DFRC systems
Ziheng Zheng, Xiang Liu, Tianyao Huang +2
It is a fundamental problem to analyse the performance bound of multiple-input multiple-output (MIMO) dual-functional radar-communication (DFRC) systems. To this end, we derive a p…
Joint Radar-Communications Strategies for Autonomous Vehicles
Dingyou Ma, Nir Shlezinger, Tianyao Huang +2
Self-driving cars constantly asses their environment in order to choose routes, comply with traffic regulations, and avoid hazards. To that aim, such vehicles are equipped with wir…
Analysis of Frequency Agile Radar via Compressed Sensing
Tianyao Huang, Yimin Liu, Xingyu Xu +2
Frequency agile radar (FAR) is known to have excellent electronic counter-countermeasures (ECCM) performance and the potential to realize spectrum sharing in dense electromagnetic…
DOA Estimation of Coherent Signals on Coprime Arrays Exploiting Fourth-Order Cumulants
Yang Hu, Yimin Liu, Xiqin Wang
This paper considers the problem of direction-of-arrival (DOA) estimation of coherent signals on passive coprime arrays, where we resort to the fourth-order cumulants of the receiv…
On Clutter Ranks of Frequency Diverse Radar Waveforms
Yimin Liu, Le Xiao, Xiqin Wang +1
Frequency diverse (FD) radar waveforms are attractive in radar research and practice. By combining two typical FD waveforms, the frequency diverse array (FDA) and the stepped-frequ…
The Random Frequency Diverse Array: A New Antenna Structure for Uncoupled Direction-Range Indication in Active Sensing
Yimin Liu, Hang Ruan, Lei Wang +1
In this paper, we propose a new type of array antenna, termed the Random Frequency Diverse Array (RFDA), for an uncoupled indication of target direction and range with low system c…
High Range Resolution Profiling in Missing Data Case: A New Approach
Yang Hu, Huadong Meng, Yimin Liu +1
We have proposed a novel method for Synthetic High Range Resolution (HRR) profiling, under the condition of missing frequency domain samples. This new approach estimates the autoco…
Fundamental Limits of HRR Profiling and Velocity Compensation For Stepped-Frequency Waveforms
Yimin Liu, Xiqin Wang, Tianyao Huang
The stepped-frequency (SF) waveform is an effective way to achieve high range resolution (HRR) in modern radars. In this paper, we determine some fundamental limits of SF waveforms…
Extended Range Profiling in Stepped-Frequency Radar with Sparse Recovery
Yang Hu, Yimin Liu, Huadong Meng +1
The newly emerging theory of compressed sensing (CS) enables restoring a sparse signal from inadequate number of linear projections. Based on compressed sensing theory, a new algor…
