Analyses of the geolocation accuracy that can be obtained from shipborne sensors by use of time difference of arrival (TDOA), scanphase, and angle of arrival (AOA) measurements
Høye, Gudrun (2010)We have performed a theoretical study of the geolocation accuracy that can be obtained from shipborne sensors by use of the localization methods: 1) time difference of arrival (TDOA), 2) scanphase, and 3) angle of arrival ... -
Electromagnetic shadow effects behind wind turbines
Høye, Gudrun (2007)The development of wind farms may sometimes conflict with Defence interests by degrading the performance of Defence installations such as radars or telecommunications systems. This report has studied the potential problem ... -
EUCLID JP 9.16: Space-based AIS reception for ship identification
Høye, Gudrun; Narheim, Bjørn T.; Eriksen, Torkild; Meland, Bente Jensløkken (2004)This report documents the results of Work element 3100 “Space-based AIS reception for ship identification” of the WEAG study JP 9.16 “Emerging Satellite Technologies, System Trends and Space Utilization”. The Automatic ... -
A method for restoring data in a hyperspectral imaging system with large keystone without loss of spatial resolution
Høye, Gudrun; Fridman, Andrei (2009)This report proposes a new method of keystone correction in the postprocessing of hyperspectral images. Unlike conventional resampling the proposed method does not introduce any loss of resolution. A hardware modification ... -
NSAT-1: nye momenter vedrørende kooperative overvåkningssystemer, flerfrekvent sensor samt havbølgers innvirkning på deteksjon og dekning
Høye, Gudrun; Eriksen, Torkild; Wahl, Terje; Lyngvi, Aleksander; Narheim, Bjørn T. (2001)This report complements the NSAT-1 Phase-A Report with a discussion of three important topics. These are: (1) The emerging cooperative maritime surveillance systems. (2) The possibility of a dual-band NSAT sensor for ... -
Observation modelling and detection probability for space-based AIS reception - extended observation area
Høye, Gudrun (2005)This report evaluates the performance with respect to ship detection probability for a space-based AIS system. The report continues the work of a previous report that studied the ship detection probability for space-based ... -
Performance analysis of the proposed new restoring camera for hyperspectral imaging
Høye, Gudrun; Fridman, Andrei (2010)This report investigates the performance of the proposed new restoring camera for hyperspectral imaging. The suggested camera will eliminate keystone in the postprocessing of the data with no resolution loss and will be ... -
Prosjekt 1013 Vindkraftutbyggingens påvirkning på Forsvarets elektromagnetiske systemet (VINDKRAFT) - sluttrapport
Meland, Bente Jensløkken; Øhra, Hans; Høye, Gudrun; Nilssen, Eivind Bergh; Søderblom, Morten; Mjanger, Morten; Otnes, Roald; Kristoffersen, Stein; Sparr, Trygve; Tollisen, Steffen; Storhaug (2007)Vindkraftutbyggingen er i full gang – også i Norge. Det har gjennom studier og feltforsøk i flere land vist seg at vindmøller har innvirkning på ulike elektromagnetiske systemer. Dette kommer av at vindmøllene er store, ... -
Pulse Descriptor Word (PDW) simulator - version 1.0
Høye, Gudrun; Opland, Eirik Jensen (2013-04-12)When developing pulse handling algorithms, a developer may face various problems with respect to the use of real data to test his or her algorithms. Some of these problems can be solved by using simulated data instead (or ... -
Ship detection probability analysis for a possible long-range AIS system
Høye, Gudrun (2005)There is an increasing requirement for global tracking of sea-going vessels. This report investigates the possibility of optimising the existing Universal Shipborne Automatic Identification System (AIS) for long-range AIS ... -
Space-based AIS : theoretical considerations and system parameter optimization
Høye, Gudrun (2006)The recently introduced Universal Automatic Identification System (AIS) is a ship-to-ship and ship-to-shore reporting system based on broadcasting of messages in the maritime VHF band. The AIS messages could also be ... -
Wind Turbines and Electromagnetic Systems (WTES) - software documentation
Meland, Bente Jensløkken; Nilssen, Eivind Bergh; Høye, Gudrun; Mjanger, Morten; Kristoffersen, Stein (2007)This report contains a description of the software developed by the FFI-project 1013 “Effekt av vindkraftutbygging på radiosamband og radar (VINDKRAFT)” (The effect of windmill development on telecommunication and ...
