AbstractThe Seasat and Shuttle imaging radars flown in the 1970s and 1980s established a strong scientific and technical base for a number of imaging radars that are flying or under development. Recent advances in understanding wave‐surface interactions, utilization of multispectral and polarimetric data, as well as advances in microwave and electronic

The preceding chapters have devoted some detail to the fundamental aspects of radar: transmission/reception; antennas; waveforms; propagation; RCS; SNR; detection; and accuracy of measurement of range, velocity, and angular position. This chapter combines those fundamentals and considers the particular advantage of applying those techniques to the case

The purpose of this chapter is to give background material for a better understanding of remote sensing in the microwave region which differs quite substantially from techniques used in the optical region. Whereas those systems operating in the visible spectrum detect the reflected solar radiation, the radar systems provide their own sources of ...

It took almost exactly 100 years from Maxwell's first conception of the theory of electro-magnetic waves and the subsequent experimental proof by Hertz in the nineteenth century until the first patent on Doppler Beam Sharpening (DBS) was issued to Wiley in 1965.

Fractures In Limestone Imaged By Radar
11th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 1998Radar data collected along profiles and in grids have assisted in identifying subsurface pathways that might carry motor fuel known to be contaminating domestic water wells. Disruptions of reflections were visible in conventional radar profiles were interpreted as fractures zone in limestone bedrock. Radar data acquired in a grid over zones where these

Understanding remote sensing with imaging radar can be more difficult than with optical imaging because the technology itself is more complicated and the image data recorded is more varied. Since there are so many concepts and techniques to be assimilated, this chapter provides an overview of the topic as a framework for the later chapters.

UAV radar imaging for target detection
Multimodal Sensing: Technologies and Applications, 2019The paper deals with subsurface imaging via radar systems mounted onboard aerial platforms. Specifically, the attention is focused on a radar prototype installed on a small unmanned aerial vehicle (S-UAV), previously proposed by few of the authors. In particular, the challenges in terms of electromagnetic modeling and flight dynamics knowledge and ...

The principal goal of remote sensing is to interpret the data recorded in order to understand the region being imaged; interpretation can be based on qualitative or quantitative methods of analysis. Analyst expertise allows qualitative information extraction through photointerpretive methods in which visual clues around structure and contrast are used.

Future Trends in Automotive Radar / Imaging Radar
28th European Microwave Conference, 1998, 1998There is a growing interest of car manufacturers in sensors monitoring the car's surrounding area in order to improve safety systems from mere crash survival to crash prediction or prevention by early detection of hazardous situations. Therefore radar sensors have been intensively investigated for many years.
