Foundational principles for large scale inference: Illustrations through correlation mining [PDF]

open access: yes, 2015
When can reliable inference be drawn in the "Big Data" context? This paper presents a framework for answering this fundamental question in the context of correlation mining, with implications for general large scale inference.

Joint 2‐D LFM Modulation and Mismatched Filter Design in Dual‐Function Radar‐Communication System

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper proposes a joint 2‐D LFM modulation and mismatched filtering design for military‐grade dual‐function radar‐communication systems. The novel scheme modulates data onto both the initial frequency and chirp rate of LFM pulses, boosting data rates whilst preserving the constant‐envelope property critical for high‐power transmission.

Research on Evaluator Education and Training: Conceptual and Practical Bounds for a Scholarship of Teaching and Learning (SoTL)

open access: yesNew Directions for Evaluation, Volume 2025, Issue 187, Page 59-66, Fall 2025.
ABSTRACT In this article, we contextualize research on evaluator education and training (RoEET) within its historical context by grounding it in a RoE framework posed by Mark and a landscape analysis by King and Ayoo. We then link RoEET with contemporary views on philosophical, applied, and empirical dimensions of the scholarship of teaching and ...

FPGA IMPLEMENTATION OF SPACE-TIME ADAPTIVE PROCESSING (STAP) ALGORITHM FOR TARGET DETECTION IN PASSIVE RADARS

open access: yesProgress In Electromagnetics Research C, 2013
Space-Time Adaptive Processing (STAP) algorithm has recently been used in Passive Bi-static Radars (PBR) because it removes the clutter and non-cooperative transmitter efiectively making the target detection easy in harsh environments like air-ground. Real- time implementation of STAP is a very challenging task as it is computationally-intensive, time ...

Anti-jamming techniques for multichannel SAR imaging [PDF]

open access: yes, 2004
An airborne broadband jammer present in the mainbeam of a Synthetic Aperture Radar (SAR) can potentially destroy a large region of the SAR image. In addition to this, multipath reflections from the ground, known as hotclutter or terrain scattered ...

Optimizing the number of players and training bout durations in soccer small‐sided games: Effects on mood balance and technical performance

open access: yesEuropean Journal of Sport Science, Volume 25, Issue 3, March 2025.
Abstract This study aimed to determine the effects of different bout durations (1 × 12 min, 2 × 6 min and 3 × 4 min) of three‐a‐side (3vs3) and four‐a‐side (4vs4) small sided games (SSGs) with goalkeepers, on the profile of mood state (POMS) scores, and technical performance (percentage of successful passes, percentage of successful tackles, percentage

Deterministic-aided single dataset STAP method based on sparse recovery in heterogeneous clutter environments

open access: yesEURASIP Journal on Advances in Signal Processing, 2018
Traditional space-time adaptive processing (STAP) usually needs many independent and identically distributed (i.i.d) training datasets for estimating clutter covariance matrix (CCM).
