A neural classifier for radar images
1996Goal of our work has been to design a Neural Network, based on the Counterpropagation Network, able to solve the classification problem in a multi-radar system.

Radar Imaging for Maritime Observation
2018Radar imaging is one of the most important tools for monitoring the sea surface. This book presents the most recent radar signal processing techniques and innovative radar concepts. The first part of the book discusses mathematical details of both SAR and ISAR techniques.

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

Why is there so much interest in space radar systems? Radar is the way to monitor changing events in a reliable manner as it is largely independent of weather – particularly useful for Europe which is so often widely cloud-covered.

On a Bayesian approach to coherent radar imaging
International Journal of Imaging Systems and Technology, 1992AbstractIn coherent imaging the object of interest is complex but only its amplitude is to be estimated. The object phase yields nuisance variables and in a proper Bayesian approach it is necessary to obtain a phaseless likelihood function. We investigate a two‐dimensional case in which the target object is modelled as a collection of point scatterers ...

Engineering multirate convolutions for radar imaging
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002We present a schematic design methodology for multirate convolution systems, based on combined algorithmic development and architecture design. It allows us to map the algebraic specification of a long convolution algorithm directly onto efficient fast convolution hardware based on short FFT processor elements or dedicated VLSI processors.

A single-chip false target radar image generator for countering wideband imaging radars
IEEE Journal of Solid-State Circuits, 2002This paper describes the theory, design, implementation, simulation, and testing of an ASIC capable of generating false target radar images for countering wideband synthetic aperture and inverse synthetic aperture imaging radars. The 5.5 /spl times/ 6.1 mm IC has 81632 transistors, 132 I/O pins, and consumes 0.132 W at 70 MHz from a 3.3-V supply.

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 ...

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.
