Achieving Robust Compressive Sensing Seismic Acquisition with a Two-Step Sampling Approach

Sensors, 2023
The compressive sensing (CS) framework offers a cost-effective alternative to dense alias-free sampling. Designing seismic layouts based on the CS technique imposes the use of specific sampling patterns in addition to the logistical and geophysical ...

Fast signal reconstruction and recognition algorithm based on cascading redundant dictionary and block sparsity for compressed sensing radar receiver

The Journal of Engineering, 2019
The compressed sensing (CS) radar receiver based on the theory of CS has a great advantage in receiving wide-band signal and can receive high-frequency radar signal at a sampling rate far lower than the traditional receiver.

Signal Recovery From Unlabeled Samples [PDF]

IEEE Transactions on Signal Processing, 2017
In this paper, we study the recovery of a signal from a set of noisy linear projections (measurements), when such projections are unlabeled, that is, the correspondence between the measurements and the set of projection vectors (i.e., the rows of the measurement matrix) is not known a priori.

Insect detection and density estimation based on a Ku-band scanning entomological radar

The Journal of Engineering, 2019
Entomological radars need to address the problem of insect density estimation. Here, a Ku-band experimental entomological radar with two-dimensional scanning mode is used to collect insect echo data.

Dynamic range analysis of one-bit compressive sampling with time-varying thresholds

The Journal of Engineering, 2019
From the point of view of statistical signal processing, the dynamic range for one-bit quantisers with time-varying thresholds is studied. Maximum tolerable amplitudes, minimum detectable amplitudes and dynamic ranges of this one-bit sampling approach ...

Quantitative estimation of sampling uncertainties for mycotoxins in cereal shipments [PDF]

, 2012
Many countries receive shipments of bulk cereals from primary producers. There is a volume of work that is ongoing that seeks to arrive at appropriate standards for the quality of the shipments and the means to assess the shipments as they are out-loaded.

Modelling of Non-ideal Signal Sampling via Averaging Operation and Spectrum of Sampled Signal Predicted by this Model [PDF]

TransNav, 2022
In this paper, a novel model of a non-ideal signal sampling via a local, periodic averaging operation is present-ed. The spectrum of a sampled signal predicted by this model is also analysed as well as compared with a one following from another model.
