The administration of the University of Siegen has supported our team by giving us access to the roof of the ZESS building to carry out our experiments. The picture shows the state at the beginning of the project. Now we can start placing our antennas …
28. November 2019 by Holger Nies | Comments Off on Passive Radar using Geosynchronous Satellites
In contrast to our high-end HITCHHIKER receiver system, we started investigating in a low cost and permanent available setup for the acquisition of radar signals. We are looking for a solution for continuous observation of small local areas which cannot be satisfied by the current satellite programs. Finally, we decided to use the signals transmitted by geosynchronous broadcasting satellites (e.g., SES-ASTRA and EUTELSAT HOT BIRD) as source for our passive receiver system. The receiver is based on a two channel Software Defined Radio (SDR) for tuning the desired signal to baseband and the sampling of the data by the analog-to-digital converter.
The main objective of the DFG funded project is the experimental verification of a parasitic multistatic radar concept using geostationary transmitters of opportunity. Further information about the project and system design you will find in the poster below.

This video shows the result of an stationary Radar Experiment. The 500MHz Noise Radar Data was processed using a rudimentary ISAR processor utilizing OpenStreetMap Road Information. The Target is a 17m articulated truck. The left part shows the radar signals in range-doppler domain. On the right part we have the ground mapped ISAR video.
The EUSAR, European Conference on Synthetic Aperture Radar, is the world’s leading international Conference dedicated to Synthetic Aperture Radar techniques, technology and applications. Between the 23rd and 26th of April 2012 we attended the EUSAR 2012 in Nürnberg with an … Continue reading →
We have recently started blogging on the HITCHHIKER bistatic radar experiment. In the future you will find news regarding the project here. Information on the project itself can be found on the project page. The team is introduced on the … Continue reading →
