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

| 0 comments

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.

Since 2009 I'm working as a scientific coworker at the Center for Sensorsystems (ZESS) for the HITCHHIKER project. My work is related to the hardware and software development as well as the signal processing for radar imaging.
