Future bi-and multistatic SAR systems could support the scientific community and the commercial market with an additional and powerful tool for imaging and exploration of interesting areas on earth. With the diversity of geometries between transmitter and receivers one can achieve for instance improvements in scene classification, extractions of particular features, and cost reduction. New experiments are necessary to investigate the advantages as well as the problems of bi-and multistatic SAR systems. This paper describes the bistatic use of the spaceborne SAR system TerraSAR-X for future spaceborne/airborne SAR exploration. TerraSAR-X will illuminate a particular scene while the receiver, the airborne SAR system PAMIR, will collect the reflected signals on board of an aircraft.

“…YBRID bi-static SAR, formed by a space borne illuminator and a receiver mounted on an aircraft [1], is a new type of bi-static synthetic aperture radar. It attracts a large number of researcher's attention due to its numerous advantages such as the invulnerability, the flexibility and the high signal-to-noise ratio [2].…”

We present a modified algorithm for temporal alignment employed in hybrid bi-static SAR, composed of a space borne transmitter and an airborne receiver, based on an algorithm for space-surface bi-static SAR. The mathematical model in the algorithm for space-surface bi-static SAR is modified due to the separation of the positions measurement devices. Simulation is performed to validate the precision of the proposed algorithm. The result after compression is good and satisfactory. Contrarily the compression result before compensation shows bad characteristics such as the displacement of the image, the degradation of the azimuth resolution and the decrease of the side lobe ratio.

“…In case of the planned hybrid (satellite/airborne) experiment [7], where the satellite has an orbit velocity of about 7.6 km/s compared with only 0.1 km/s of the airborne platform, there will be a difference in the velocities of both antenna footprints in the order of 70. Moreover, due to the high velocity of the satellite (TerraSAR-X), the overlap of the antenna footprints will be just a few seconds in maximum.…”

In future bistatic SAR experiments 1 the overlapping of transmitter and receiver antenna footprints is, due to the different trajectories and velocities of the involved platforms, an issue. In this paper we focus on the planned hybrid experiment with an aircraft and TerraSAR-X as carrier platforms. The effect of unknown rotations about the body-axes on the tie point of the antenna pointing vector in Earth's local tangent plane is described. Simulation results based on possible aircraft and satellite parameters are presented and discussed. Based on the suggested geometric modeling and results, positioning and attitude determination requirements can be easily derived for different constellations.
