iFURTHER Project - A Cognitive Network of HF Radars for Europe Defence
Stéphane Saillant;Dominik Bok;Jean-Philippe Molinié;Apostolos Leventis;Piotr Samczynski;Philippe Brouard;Anna Lisa Saverino;Amerigo Capria;Yoann Paichard
2023 IEEE International Radar Conference (RADAR)
Year: 2023 | Conference Paper |
Cited by: Papers (4)
This paper presents the European project named iFURTHER that focuses on multi-site HF-OTH-R approaches. Facing the new military threats, the European Union seeks to develop disruptive defence systems that benefit from a new robust capability to complement existing surveillance systems. The iFURTHER project conceptualises the idea of a cognitive network of HF radars over Europe that provides the ca...Show More
Coherency limits and synchronisation of a netted radar system using USRPs as nodes
Ferran Valdes Crespi;Angel Slavov;Dominik Bok;Stephan Sandenbergh;Peter Knott;Daniel O’Hagan
2023 IEEE International Radar Conference (RADAR)
Year: 2023 | Conference Paper |
Cited by: Papers (1)
This paper intends to further evaluate the synchronisation capabilities of multiple networked USRPs. We obtained a priori knowledge of the USRP’s coherency limits between daughterboards within a single device and presented such results in our previous work [1]. The final aim of this work is to build a versatile networked radar system which may take advantage of the transceiver capabilities of its ...Show More
Coherency limits of different transceivers within USRP X310 as a radar node
Angel Slavov;Ferran Valdes Crespi;Stephan Sandenbergh;Dominik Bok;Daniel O’Hagan;Peter Knott
Diverse literature agrees on the advantages that multiple antennas and, thereby, multi-channel diversity brings into a modern radar system. Modern multichannel USRPs are suitable platforms for realisation of diverse radar demonstrators. However, coherency plays an essential role for accurate radar detection and tracking. This paper focuses on determining the stability of multi-channel TwinRX and U...Show More
Relatively Moving Target Return Emulation for high Coherently Processed Time-Bandwidth Products
2022 IEEE Radar Conference (RadarConf22)
Year: 2022 | Conference Paper |
The accurate modelling of relative target motion is essential for coherent radar processing and suitable emulation approaches for radar testing. Special consideration will be required if an instantaneously wide signal spectrum is processed over a long timespan and a non-stationary target return migrates in relative range. Thereby, a fast moving isotropic point scatterer will span concurrently a se...Show More
Geometry-Induced Acceleration in Case of a Straight-Line Target Trajectory in Bistatic Radar
Bistatic radar signal processing often assumes a constant velocity for target detection. The bistatic geometry alters, however, the effectively measurable velocity in relation to the target position and motion even if the target has a constant ground speed. Hence, the bistatic geometry induces instantaneous bistatic target acceleration. This is especially the case if a straight-line target traject...Show More
Synchronisation is an important part of radar signal processing and in particular for multistatic radar systems. On the one hand, it is critical to enhance the signal processing to improve the system performance, on the other hand, it supports the multisite distribution as it is done for multistatic systems. In the case of an orthogonal-frequency division multiplexing (OFDM) signal with specified ...Show More
Aspects of Next Generation Sensor/Radar Networks
Matthias Weiß;Stephan Sandenbergh;Ferran Valdes;Peter Müller;Dominik Bok;Michael Kohler;Daniel O’Hagan;Peter Knott
2019 20th International Radar Symposium (IRS)
Year: 2019 | Conference Paper |
Distributed sensor/radar networks offers several benefits over monostatic systems. For instance, as targets are observed from different aspects angles the detection performance and estimation accuracy of position and speed (Doppler) is improved. Furthermore, a sensor network is able to cope with an increased number of targets. Due to this the interest in such systems has increased over the past ye...Show More
Reconstruction and Reciprocal Filter of OFDM Waveforms for DVB-T2 Based Passive Radar
2018 International Conference on Radar (RADAR)
Year: 2018 | Conference Paper |
The digital video broadcasting (DVB) transmission standard DVB-T2 published by the ETSI [1] enables a new digital television format for terrestrial transmissions. It currently supersedes DVB-T transmission systems. The introduction of a complicated frame and modulation structure raises several demands to process DVB-T2 in passive radar applications. This includes challenges for the reconstruction ...Show More
A multistatic passive coherent location system with receiver location constraints
2017 18th International Radar Symposium (IRS)
Year: 2017 | Conference Paper |
A multistatic passive coherent location system has been designed during an eight month lasting trial starting in the end of 2015. The demonstration system exploits the regional single-frequency network (SFN) of DVB-T transmissions from two transmit stations in the area of Munich, Germany. It features multiple pre-existing receiving sites of a TDOA-based passive emitter tracking system to localize ...Show More
