The composite scattering model for radar sea return [PDF]

, 1972
A composite scattering model, suitable for explaining the behavior of measured scattering cross sections of the ocean surface, is presented. Furthermore, utilizing this scattering model, the spectrums of the small gravity, gravity-capillary, waves will ...

Resource allocation and growth strategies in a multi‐plant firm: Kanegafuchi Spinners in the early 20th century

Strategic Management Journal, EarlyView., 2023
Abstract Research Summary Using detailed plant‐ and individual‐level data from a major Japanese cotton spinning company in the early 20th century, we examine the within‐firm allocation of skilled human capital in conjunction with investment in physical capital, accompanying the firm's evolving strategic priorities.

Does education policy affect teachers' learning needs? An international comparison of trends in teachers' continuing professional learning needs in secondary schools in Australia, England, Japan and the Netherlands

British Educational Research Journal, EarlyView.
Abstract Education policy changes are believed to influence teachers' continuing professional learning (CPL) needs, but there is limited empirical evidence to support these claims. This lack of deep understanding has significant practical implications. This study used a new circular conceptual framework to analyse teachers' CPL needs. Leveraging public

Academic misconduct appeal services in China: Platform logics, self‐platformization and implications for integrity education

British Educational Research Journal, EarlyView.
Abstract Academic misconduct appeal services have quietly emerged within China's education marketplace, with commercial agencies promoting themselves on social media to assist international students facing misconduct hearings. While existing research on academic integrity has emphasized prevention and detection, far less attention has been paid to what

Compound-Gaussian Clutter Model with Weibull-Distributed Textures and Parameter Estimation

Remote Sensing
Compound-Gaussian models (CGMs) are widely used to characterize sea clutter. Various types of texture distributions have been developed so that the CGMs can cover sea clutter in different conditions.

A Novel Main-Lobe Cancellation Method Based on a Single Notch Space Filter and Optimized Correlation Analysis Strategy

International Journal of Antennas and Propagation, 2019
The high-frequency hybrid sky-surface wave radar (HFSSWR) is a new kind of over-the-horizon radar system. Combining the advantages of both the sky wave radar and the surface wave radar, HFSSWR has drawn much attention in recent years.

MIMO Radar Target Localization and Performance Evaluation under SIRP Clutter

, 2016
Multiple-input multiple-output (MIMO) radar has become a thriving subject of research during the past decades. In the MIMO radar context, it is sometimes more accurate to model the radar clutter as a non-Gaussian process, more specifically, by using the ...

Sea clutter simulation

, 2012
This dissertation presents the results of a study, the aim of which was the prediction of sea clutter characteristics including the temporal properties of the return signals as observed by a maritime surveillance radar system. The compound K distribution model used to generate clutter amplitude statistic enables the simulation of sea clutter with a ...
