Amplitude suppression of nongaussian sea clutter in a noncoherent bandpass path of the receiver
Известия высших учебных заведений России: Радиоэлектроника, 2016 The method of non-linear amplitude suppression of radar clutter from a sea surface in a noncoherent band path of the receiver is considered. The model of the most adequate nongaussian a radar clutter from the rough sea surface which envelope is based on ...

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat
Integrative Zoology, EarlyView.After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

Adjacent Infrared Multitarget Detection Using Robust Background Estimation [PDF]
Small target detection is very important for infrared search and track (IRST) problems. Grouped targets are difficult to detect using the conventional constant false alarm rate (CFAR) detection method.

Critical Quarterly, EarlyView.Abstract ‘I have to share a bathroom’, I had so often murmured, almost with shame, as if I personally had been found unworthy of a bathroom of my own. Barbara Pym, Excellent Women (1952) For a single woman of a certain age, living alone in postwar London, austerity was more than a set of political and economic imperatives.

Comparative Study on Chaos Identification of Ionospheric Clutter From HFSWR
IEEE Access, 2019 In addition to target echoes, high frequency surface wave radar (HFSWR) receives sea and ionospheric clutter. Among these clutters, the ionospheric clutter is dominant and significantly affects the detection performance of HFSWR, particularly when the ...

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’.

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 ...
