Micro-Doppler Clutter Removal Method Based on the Cancelation of Sliding STFT Spectrogram
Leida xuebao, 2022 Micro-motion clutter typically exhibits significant Doppler broadening, raises the noise floor, and annihilates weak targets, resulting in false alarms and missed detections.

Solving multiple windowed STFT phase retrieval problems in phase and amplitude respectively
Applied Mathematics in Science and Engineering, 2022 We study the Phase Retrieval (PR) problem under the phaseless short-time Fourier transform (STFT) measurements. This paper proposes a novel algorithm named PAR to solve the STFT PR problem in phase and amplitude respectively with a milder retrieval ...

Two Dimensional Short Time Hartley Transforms
Sultan Qaboos University Journal for Science, 2016 The Hartley transform, as in the case of the Fourier transform, is not suitably applicable to non-stationary representations of signals whose statistical properties change as a function of time.

A Weak Target Detection Algorithm IAR-STFT Based on Correlated K-distribution Sea Clutter Model [PDF]
Radioengineering, 2023 The detection performance of weak target on sea is affected by the special effects of sea clutter amplitude. Aiming at the time and space correlated of sea clutter, the correlated K-distribution sea clutter model is established by the sphere invariant ...
