Radar as a coherent imager is physically based on the wave equations that govern the behavior of wave-targets interactions through the process of radiation, transmission, propagation, and reflection/refraction. This chapter briefly introduces the stochastic wave equations at a minimum but sufficient level to serve as fundamentals of radar imaging ...

Radar Systems (RADAR 97), 1997
In this paper an algorithm based on emerging data compression techniques and suitably adapted to the radar data of a VTS (Vessel Traffic Service) System is presented. The basic idea derives from the JPEG (Joint Photographic Experts Group) standard which converts image data to a spatial frequency representation using a 2-D discrete cosine transform (DCT)

IEEE Transactions on Geoscience Electronics, 1978
A radar image simulation model, which can be used to aid interpretation of images and information extraction from images, has been developed and implemented on a digital computer. The model, called the "Point Scattering Model," is a mathematically rigorous treatment of the stochastic process described by the closed system consisting of the radar ...

16th European Microwave Conference, 1986, 1986
This paper is concerned with the problem of obtaining an image by means of a spatially coherent radar signal processing. After a brief review of the above technique, the problems of motion compensation (target tracking) and of 2D-Fourier inversion, arising in practical realisations, are discussed. In addition, the possibility of extending the theory to

International Journal of Imaging Systems and Technology, 1991
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 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 ...

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.

Radar target imaging using distributed radar networks
2009 IEEE Antennas and Propagation Society International Symposium, 2009Target images can be clearly reconstructed from the monostatic and bistatic range profiles generated by a DRN with enough radar sensors. Because the images are instantly formulated, no synthetic aperture processing or motion compensation is needed.
