Sensors and methods for weather-independent remote sensing with microwaves

Sensors and methods of radar and microwave radiometry which operate in the millimeter wave range are discussed. The properties of electromagnetic waves are discussed as well as the resolution capacity and measurement accuracy of sensor systems

Ausgewaehlte Beispiele zur Anwendung von Radarsatellitendaten

SAR-Satelliten finden Anwendung in zahlreichen Disziplinen der Wissenschaft, in operationellen Bereichen der zivilen und mili- taerischen Sicherheit und der Umweltbeobachtung. Ozeanographie, Oekologie, Hydrologie, Geologie und Kartographie sind wesentliche Anwendungsfelder ebenso wie Zielerkennung und Aufklaerung. Ent- sprechende Beispiele gewonnen mit X-SAR/SIR-C, ERS-1/2 und Radar- sat werden gezeigt

The Joint Oberpfaffenhofen SAR Expert Facility - Objectives and Activities

The Joint Oberpfaffenhofen SAR Expert Facility is the entirety of all SAR expertise and experts available within the campus of the DLR in Oberpfaffenhofen. The AeroSensing Company is also involved. Objective of the facility is to accomplish the development of SAR systems, enhance the state of the art and lead SAR to respective applications

SAR, von der Datenaufnahme zum Resultat

Einer grundsätzlichen Erläuterung des SAR-Prinzips werden Anwendungsmöglichkeiten von SAR zur Fernerkundung der Erde vorgestellt und anhand von Meergebnissen und Beispielen erläutert. Die dabei eingesetzten SAR-Verfahren und Moden wie z.B. Streifen-Modus, SAR-Interferometrie, Bewegtzieltechniken, Transponder-Techniken sowie Inverse SAR Verfahren werden erklärt. Beispiele zur Nutzung und Anwendung bilden den Abschluß

Verification Using Spaceborne Microwave Imaging

SAR images are particularly suited for verification purposes because their image resolution capabilities are independent of weather conditions, surface penetration, and optical visibility. Their restrictions are related to data handling and power re- quirements. The respective state of the art is presented and pro- jections for future development of SAR are made on the basis of requirements for verification and desaster monitoring

SAR Technique and Technology, its Present State of the Art with Respect to User Requirements

The present state of the art for civilian spaceborne and airborne SAR will be shown using tables which list the requirements as well as the specifications of present systems, some results are given for special applications exemplarically

SAR Pecularities, Ambiguities and Constraints.

SAR and RAR will be compared with respect to range dependence of SNR azimuth resolution, influence of platform and target velocity and acceleration, azimuth and range ambiguities pulse repetition frequency limitations and phase errors
