Introduction to Synthetic Aperture Radar - pankusoft - 08-16-2017 Introduction to Synthetic Aperture Radar [attachment=16605] GENERAL FACTS ABOUT SAR Today, synthetic aperture radar (SAR) plays an important role in military ground surveillance and earth observation. Since the late eighties a couple of SAR-systems have been developed for both space and airborne operation. The underlying radar principle offers advantages compared to competing sensors in infrared or visible spectral area. Introduction to Synthetic Aperture Radar (SAR) rain are impenetrable for this wavelength. Infrared sensors which are applicable day and night are even more sensitive on weather conditions. Consequently, radar sensors represent a completion of the sensor collection for remote sensing. Beyond the overall availability of SAR images there are further pros for the utilization of radar. The coherent nature of SAR enables the user to process images of subsequent overflights for interferometrical analyses. Depending on the radar wavelength the radar signal will be reflected by vegetation or the ground structure. Circumstances It has been mentioned that the propagation and reflection of electromagnetic waves strongly depends on its frequency. Figure 1 shows the atmospheric transmission for a wide frequency interval. SAR systems for wide area surveillance have to operate in frequency areas with minimal attenuation. Beyond the Ka-band only short range systems are realizable. Advantages of systems with a higher frequency are a reduced system size and a simplified processing. X,- C- and L-band are very common for airborne and spaceborne sensors.
