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…
A Volume Correlation Subspace Detector for signals buried in unknown clutter
Hailong Shi, Hao Zhang, Xiqin Wang
Detecting the presence of target subspace signals with unknown clutters is a well-known hard problem encountered in various signal processing applications. Traditional methods fail…
A TDOA technique with Super-Resolution based on the Volume Cross-Correlation Function
Hailong Shi, Hao Zhang, Xiqin Wang
Time Difference of Arrival (TDOA) is widely used in wireless localization systems. Among the enormous approaches of TDOA, high resolution TDOA algorithms have drawn much attention…
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…
