Resolution enhancement for ISAR imaging via improved statistical compressive sensing

Developing compressed sensing (CS) theory reveals that optimal reconstruction of an unknown signal can be achieved from very limited observations by utilizing signal sparsity. For inverse synthetic aperture radar (ISAR), the image of an interesting target is generally constructed by limited strong scattering centers, representing strong spatial sparsity. Such prior sparsity intrinsically paves ...

An event-based method for microphone array speech enhancement

This paper presents the Multi-Channel Multi-Pulse (MCMP) algorithm for the enhancement of speech degraded by reverberations and additive noise. The enhanced speech is synthesized from a sequence of impulses exciting a linear predictive lter. The excitation signal is computed from a nonlinear process which uses impulse clustering of the multi-channel speech data to discriminate portions of the l...

Sensitivity Enhancement Using Parametric Amplification in a Resonant Sensing Array

In this work we describe the parametric amplification of a multi-degree of freedom resonant chemical mass sensing array. We experimentally demonstrate that parametric forcing can be employed to increase the effective resonant quality factor of the array structure via an applied base motion containing the appropriate frequency content. Applying parametric forcing in this manner is simple and ali...

Analog Array Processor with Digital Resolution Enhancement and Offset Compensation

Abstract — A mixed-mode inner-product vector processor is presented. It performs high-dimensional matrix-vector multiplication on a fine-grain analog array and has a purely-digital interface. The array incorporates charge-mode analog computational cells and row-parallel analog-to-digital converters (ADC). Each of the cells includes a dynamic storage element and a charge injection device computi...
