ABSTRACT

During a measurement campaign of the NATO research group SET-250 SAR measurements have been performed with two SAR sensors of Fraunhofer FHR using different frequency bands: the MIRANDA-94 and the PAMIR-Ka. We processed the data to create SAR images with approximately 10 cm resolution in both range and cross range direction and analysed the results. The main objective of the joint measurement campaign was to collect multi-dimensional radar data of military objects, where the designation ‘multi-dimensional’ covered various parameters, e.g., illumination direction, frequency, polarisation, and time. Beyond the mentioned SAR imaging the data of each sensor was used with respect to specific additional capabilities. While MIRANDA-94 was used to evaluate the benefit of polarimetric measurements, we varied PAMIR-Ka processing parameters to evaluate the advantages of multiple looks with respect to frequency and illumination direction.
