“…Such waveforms are called timevarying or nonstationary signals. They are encountered in various areas such as audio signals, synthetic aperture radar, and machinery [9,11,12]. Recent advances dealing with nonstationary signals mainly focus on the time-frequency analysis methods, since the signals are intrinsically sparse on the time-frequency plane.…”

“…Time-frequency analysis is an effective tool to characterize nonstationary signals [11][12][13][14][15]. It reflects the time-varying properties by mapping signals into the joint time-frequency domain.…”

“…However, two non-uniform subarrays are discarded to cause DOF loss in its application due to the holes. That is to say, the DOF provided by the coprime array is not fully utilized [31][32][33][34].…”

“…erefore, designing a sub-Nyquist sampling scheme which can effectively sense the power spectrum of nonstationary signals is a challenging task. Coprime theory [35,36], which is well suited for analyzing sparsely sampled signals in case that sampling rate is far lower than the Nyquist sampling rate, has gained increasing attention in recent years. Coprime theory can be well coupled with DFT filter banks theory in temporal domain to sense the power spectrum of WSS signals [35].…”
