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.
