Space-polarization Collaborative Suppression Method for Ionospheric Clutter in HFSWR
Leida xuebao, 2016 High Frequency Surface Wave Radar (HFSWR) is able to receive surface target and low-flying aircraft echoes at a long-distance, but it suffers severely from ionospheric clutter.

Managed decline: Muddling through with the Sterling (dis)Agreements, 1968–74
The Economic History Review, EarlyView.Abstract How do policymakers manage the decline of an international currency? This paper revisits the view that the ‘Sterling Agreements’ of 1968–74 – bilateral contracts between the UK and sterling‐holding governments – marked a successful paradigm shift towards sterling's managed ‘retirement’.

Dual-channel Clutter Cancellation Processing Method via Space-time Decoupling for Airborne BiSAR
Leida xuebaoClutter suppression is an important technology for moving target indication. However, for Bistatic Synthetic Aperture Radar (BiSAR) moving target indication, traditional space-time adaptive processing and displaced phase center antenna methods cannot ...

EFFECT OF NON GAUSSIAN WEATHER CLUTTER ON PERFORMANCE OF CLUTTER-SUPPRESSION FILTERS
International Conference on Aerospace Sciences and Aviation Technology, 1985 In this paper it is investigated the performance of clutter suppression filters in non Gaussian clutter. The model chosen is Log-normal clutter and the filters considered are the optimum MTI filter and the linear prediction error filter. The performance of both types of filters in Gaussian clutter as expressed by the improvement factor (I.F) is ...

Fish and Fisheries, EarlyView.ABSTRACT Monitoring recreational fisheries is difficult: anglers are widely dispersed, gear and practices vary, and many species are involved, which leads to fragmented and scarce data. To address these issues, we developed an Artificial Intelligence (AI) pipeline that turns angler‐reported photos into standardised records of catch composition and ...

Multi‐Objective Optimization of a Hydro‐Economic Model in an Over‐Allocated Agricultural Basin
Groundwater, EarlyView.Abstract Groundwater depletion for agricultural irrigation poses significant environmental and economic challenges. This study introduces a proof‐of‐concept that combines hydro‐economic modeling, scenario‐based modeling, and multi‐objective optimization to manage pumping curtailment in an over‐allocated basin in the western United States.
