چکیده

An innovative approach to non-uniform sampling is proposed in this research paper specifically two engineering methods to sampling are proposed. Using results from statistics literature, an “optimal sampling” scheme is discussed. Information theoretic approach to nonuniform sampling formulated.

Digital Beamforming for High Resolution Wide Swath SAR Imaging

Synthetic Aperture Radar (SAR) is a wellproved instrument for remote sensing. Multi-aperture SARsystems allow for digital beamforming on receive that will enable a wide swath SAR with high azimuth resolution. In classic multi-aperture systems, stringent requirements are imposed on sensor velocity and PRF to ensure uniform sampling of the synthetic aperture. This paper shows that an unambiguous ...

Scalable VHDL Architectures for Non-uniform Sampling Driver Designs

Non-uniform sampling promises increased equivalent sampling rates with reduced overall hardware costs. Each device applying non-uniform sampling must use special circuits and architectures to achieve a correct and predictable sampling scheme with respect to time instant placement. The architecture of an ASIC implementation for non-uniform sampling varies with the application. Different boundary...

A study on the use of perturbation technique for analyzing the nonlinear forced response of piezoelectric microcantilevers

In this paper, a comparison is made between direct and indirect perturbation approaches to solve the non-linear vibration equations of a piezoelectrically actuated cantilever microbeam. In this comparison, the equation of motion is considered according to Euler-Bernoulli theory with considering the non-linear geometric and inertia terms resulted from shortening effect. In the direct perturbatio...

Non-uniform Filter Design in the Log-scale

We propose a filtering technique which takes advantage of the possibility of using a very low number of samples for both the signal and the filter transfer function thanks to non-uniform sampling. Following some previous work where we sampled non-uniformly already existing filter transfer functions, we propose now to design directly new filters in the frequency domain. They will be linear with ...
