Abstract

For airborne reconnaissance day/night/all-weather capability and high resolution of imaging radar sensors is mandatory. For the development of related processing algorithms an experimental, polarimetric 94-GHz radar has been developed using a FM/CW waveform with a bandwidth of 4000 MHz resulting in a resolution < 4 cm. The radar has been tested using the method of Inverse Synthetic Aperture in tower/turntable geometry. To be able to derive ISAR images with the full theoretically achievable resolution, a fast polar reformatting process was developed and tested with the data.
