Compressive sensing based separation of nonstationary and stationary signals overlap** in time-frequency
A compressive sensing (CS) approach for nonstationary signal separation is proposed. This
approach is motivated by challenges in radar signal processing, including separations of …

Separation and reconstruction of the rigid body and micro‐Doppler signal in ISAR part I–theory
In radar imaging, the micro‐Doppler effect is caused by fast movements of some scattering
points on the target. These movements correspond to highly non‐stationary components in …

Time-frequency analysis of micro-Doppler signals based on compressive sensing
Signals returned from an object containing fast-moving parts have Doppler frequency
modulations, called micro-Doppler effects, which produce time-varying spectral contents …
