Multi-platform campaigns open up new opportunities and allow a comparison and analysis of SAR signatures of the same area at different frequency bands and incident angles. In this paper, we make use of two different sensor systems: DLR's pulsed F-SAR

Fraunhofer FHR has participated in the international measurement campaign of the NATO research task group SET-250 with two airborne SAR systems in July 2019. The general objective of the trials was to investigate the use of multidimensional radar to

Technological advances in frequency-modulated continuous-wave (FMCW) synthetic aperture radar (SAR) and the associated miniaturization and energy efficiency make it increasingly possible to transfer SAR systems from traditional airborne platforms to

2018 19th International Radar Symposium (IRS).
In this paper, we present the upgraded MIRANDA-35 SAR system, which has been extended by three additional receiving channels. The adapted antenna configuration enables simultaneous interferometric and polarimetric SAR measurements. We describe the im

The detection and defense of Unmanned Aerial Systems (UAS) is becoming increasingly important for the protection of public and private areas. The low cost of micro- and mini-drones, the easy handling, and a considerable payload make them an excellent

2017 18th International Radar Symposium (IRS).
The airborne monitoring of scenes using unmanned or small piloted aircrafts is becoming increasingly important. Several types of airborne sensors - in the electro-optical, infrared or millimeter wave spectrum - are available for the different platfor

Up to now, the high effort involved with airborne Synthetic Aperture Radar (SAR) systems has led to the effect that SAR image processing is mostly restricted to single images of a scene. Recent developments like the MIRANDA 35 and its matching flight

Propagation above the sea surface depends on many parameters related to the meteorological and oceanographic conditions, the measurement geometry and the system parameters. In this contribution we report on an experiment performed at the Gulf of Mexi
