Focusing results and analysis of advanced bistatic SAR experiments in spaceborne or airborne/airborne or stationary configurations

This paper concentrates on the focusing results of several hybrid bistatic SAR experiments. The hybrid bistatic configurations are referred to the case that transmitter and receiver are mounted in different kinds of platforms, e.g., spaceborne/airborne, airborne/stationary, spaceborne/stationary, and so on. Recently, we have successfully performed several hybrid bistatic SAR experiments, i.e. TerraSAR/PAMIR, PAMIR/stationary, and TerraSAR/ stationary. In this paper, we will emphasize the imaging geometry, image analysis, and the frequency-domain focusing results.
