Analysis of detection performance of incoherent range walk compensation for passive radar
Finden, Erlend; Christiansen, Jonas Myhre; Lie-Svendsen, Øystein; Olsen, Karl Erik (2015)This paper analyzes the performance of an incoherent range walk compensation method for passive radar systems. The method utilizes the velocity information in the range-Doppler map, and no detection before compensation ... -
Beamforming of synthetic target signal acquired by the Atlantis PCL system
Strøm, Kyrre; Finden, Erlend; Schell, Jochen; Norheim-Næss, Idar; Lie-Svendsen, Øystein (2016-09-20)The passive coherent location system, Atlantis, is a test bed for digital beamforming at the Norwegian Defence Research Establishment (FFI). The system has functionality for real time direction of arrival (DoA) estimation. ... -
Detection performance for Incoherent Range Walk Compensation
Finden, Erlend; Christiansen, Jonas Myhre; Lie-Svendsen, Øystein; Olsen, Karl Erik (2014-11-24)FFI supports the Royal Norwegian Air Force in their acquisition of new air surveillance sensors. Improved detection performance on low observable targets may be obtained by increasing the radar dwell time on target. For ... -
DSI Suppression with Adaptive Beamforming in DVB-T Passive Radar Measurements
Strøm, Kyrre; Lie-Svendsen, Øystein; Norheim-Næss, Idar; Johnsen, Terje; Finden, Erlend; Olsen, Karl Erik (2018)Adaptive beamforming (ABF) for maximizing the signal to interference plus noise ratio (SINR) is applied to acquisitions made by a passive bistatic radar (PBR) exposed to strong direct signal interference (DSI). The DVB-T ... -
DVB-T Passive Radar Dual Polarization Measurements in the Presence of Strong Direct Signal Interference
Strøm, Kyrre; Lie-Svendsen, Øystein; Finden, Erlend; Norheim-Næss, Idar; Johnsen, Terje; Baruzzi, Aurora (2017)A dual-polarization passive bistatic radar is used to evaluate the potential benefit of cross-polarized measurements for the suppression of strong direct signal interference in the DVB-T band. The linear array antenna ... -
Imaging radar for navigation and surveillance on an autonomous unmanned ground vehicle capable of detecting obstacles obscured by vegetation
Gusland, Daniel; Torvik, Børge; Finden, Erlend; Gulbrandsen, Fredrik; Smestad, Ragnar (2019-09-16)The Norwegian Defence Research Establishment (FFI), has developed a multi purpose radar demonstrator for Intelligence, Surveillance and Reconnaissance (ISR) on the Off-road Light Autonomous Vehicle (OLAV) platform. The ... -
Passive Radar detection of small UAV over sea
Norheim-Næss, Idar; Finden, Erlend; Strøm, Kyrre (2019-07-22)During a trial over the Trondheim-fjord in Norway fall 2018, aDVB-T based passive radar system was used for detecting a small unmanned aerial vehicle (UAV) over sea. The measurements show a possible detection range of 1 ...
