HITCHHIKER unleashed

We will provide the data acquired in the HITCHHIKER experiments to other research groups free of charge. At this time two datasets are available for download. We will provide preprocessed unfocused sensor data intended for bistatic SAR processing and focused single look complex datasets in bistatic radar coordinates and ground coordinates.
You can request the data here. All data will be provided as HDF5 file format.

TerraSAR-X/TanDEM-X Toolbox for MATLAB released

A first version of our Toolbox to read the datasets provided by the TanDEM-X mission of DLR is released as Open Source software under the GPL as TanDEMXforMATLAB on GitHub.

More Information on the TanDEM-X mission can be found at the DLR Homepage.

And some more technical related content regarding the interferometric mission at the TanDEM-X Science Service System and the monostatic SAR operation at the TerraSAR-X Science Service System.

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.

EUSAR 2012: A noise based transmitter system for the HITCHHIKER project

Abstract:

The HITCHHIKER project was started in 2009 with the goal to develop a passive high resolution receiver system to perform a series of bistatic experiments using the German TerraSAR-X system as illuminator and demonstrating the feasibility of high resolution bistatic imaging with a stationary receiver.

This paper describes valuable extensions augmenting the system to a fully functional bistatic one pass interferometer to acquire high resolution DEMs on the one hand and further integrating a modular and flexible high bandwidth transmitter component with a thermal noise based signal source for waveform generation to upgrade the system to a fully operational active bi- or monostatic (standalone) SAR sensor.

A first experimental result with a noise based transmitter and the HITCHHIKER receiver and an outlook on upcoming experiments with this new system in 2012 completes the work.

EUSAR 2012

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 oral presentation entitled A noise based transmitter system for the HITCHHIKER project. This contribution describes the current status and results of the HITCHHIKER project and introduces the new transmitter system with a thermal noise based waveform.

Bachelor: Integration, Control and Characterization of a YIG Microwave Synthesizer

Zur Erzeugung des Lokaloszillatorsignals im HITCHHIKER Sendesystem soll neben weiteren Methoden auch ein Synthesizersystem basierend auf einem YIG-Oszillator eingesetzt werden. Der Synthesizer besteht dabei aus einem getrennten Oszillatormodul und der Phasenregelschleife (PLL), basierend auf dem LMX2326, welche über die serielle MICROWIRE Schnittstelle gesteuert wird.

Welcome!

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 team page.
If you have comments or questions, don’t hesitate to post.
