TL;DR: A multistatic, sea clutter and vessel database, assembled using the three node, S Band radar, known as NetRAD (for, “Netted Radar”), collected in the United Kingdom and South Africa during 2009-201 is described.
Abstract: This paper describes a multistatic, sea clutter and vessel database, assembled using the three node, S Band radar, known as NetRAD (for, “Netted Radar”). This data was collected in the United Kingdom and South Africa during 2009-201. It is the intention of the investigators and sponsors of this work to make the raw data available to individuals and organisations interested in processing this multistatic data in support of the development of the understanding of sea clutter and vessel properties in the multistatic configuration.

TL;DR: In this paper, a doubly-polarized array of connected dipoles for in-flight entertainment is presented, which is designed to simultaneously operate in the uplink and the downlink bands, with an overall bandwidth of about 30%.
Abstract: This work reports on the development and performance of a doubly-polarized array of connected dipoles for in-flight entertainment. The array is designed to simultaneously operate in the uplink and the downlink bands, with an overall bandwidth of about 30%, from 10.7 to 14.5 GHz. The array prototype comprises 16×16 elements in each polarization for a total of 512 elements. The use of a loop-shaped transformer in the feed lines and a wide angle impedance matching (WAIM) sheet allows to achieve low cross-polarization and sufficiently good matching for scanning up to ±60° in elevation for every azimuth plane.
