Abstract :
The airborne experimental multichannel SAR/GMTI system PAMIR (phased array multifunctional imaging radar) serves as a platform for the demonstration of new capabilities in surveillance and reconnaissance. The sensor is working in the X-band and features a bandwidth of 1.8 GHz, five parallel receive channels, and an active phased array antenna comprising up to 256 Vivaldi columns and T/R modules and a broadband true time delay beamforming network. The antenna is reconfigurable, e.g. to a multi-baseline aperture for interferometric modes or to an elongated aperture for GMTI purposes. This contribution presents methods and results of two advanced radar tasks, namely high resolution SAR imaging with sub-decimetre resolution and non-canonical SAR imaging in case of rapid azimuth scanning
