Time-Range Adaptive Focusing Method Based on APC and Iterative Adaptive Radon-Fourier Transform
Remote Sensing, 2022 In conventional radar signal processing, the cascade of pulse compression (i.e., matched filter) and Radon-Fourier transform (RFT) can extract the estimated scattering coefficient of the target in the range-velocity dimension through long-time coherent ...

Adaptive acoustooptic filter [PDF]
Applied Optics, 1984 A new adaptive filter utilizing acoustooptic devices in a space integrating architecture is described. Two configurations are presented; one of them, suitable for signal estimation, is shown to approximate the Wiener filter, while the other, suitable for detection, is shown to approximate the matched filter.

On Implementation and Design of Filter Banks for Subband Adaptive Systems [PDF]
, 1998 This paper introduces a polyphase implementation and design of an oversampled K-channel generalized DFT (GDFT) filter bank, which can be employed for subband adaptive filtering, and therefore is required to have a low aliasing level in the subband ...

Measuring Performance Limits of Subband Adaptive Systems [PDF]
, 1998 We discuss a method to measure the convergence limits of general subband adaptive systems due to non-ideal filter banks. Aliasing caused in such filter banks presents a distortion to the subband adaptive system which forms a lower limit for the minimum ...

Bearing Fault Signal Analysis Based on an Adaptive Multiscale Combined Morphological Filter
International Journal of Rotating Machinery, 2020 Bearing fault signal analysis is an important means of bearing fault diagnosis. To effectively eliminate noise in a fault signal, an adaptive multiscale combined morphological filter is proposed based on the theory of mathematical morphology.
