A Method for Spaceborne SAR Geolocation Based on Continuously Moving Geometry

Leida xuebao, 2013
Geolocation is a very important step in Synthetic Aperture Radar (SAR) data processing. The precision of geolocation severely affects the applications of SAR images. This paper analyzes the influences on SAR geolocation caused by the traditional “stop-go”

City-Level IP Geolocation Algorithm Based on PoP Network Topology

IEEE Access, 2018
The existing city-level IP geolocation algorithms determine the location of IP by delay measurement and landmark comparison, and thus, the geolocation ability of these algorithms is affected by the delay precision and the number of landmarks.

Transition From Primary to Secondary School: Igniting Attendance and Engagement Among Aboriginal and Torres Strait Islander Students Through National Policy Reform

Australian Journal of Social Issues, EarlyView.
ABSTRACT Australia's Closing the Gap reform aims to address disparities experienced by Aboriginal and Torres Strait Islander peoples. There are specific targets focussed on key educational transitions; yet, the transition to secondary education is not a targeted priority.

High-Resolution Spaceborne SAR Geolocation Accuracy Analysis and Error Correction

Remote Sensing
High-accuracy geolocation is crucial for high-resolution spaceborne SAR images. Most advanced SAR satellites have a theoretical geolocation accuracy better than 1 m, but this may be unrealizable with less accurate external data, such as atmospheric ...
