Estimating canola phenology using synthetic aperture radar
Remote Sensing of Environment, 2018Prolonged periods of wet soil conditions, when present during critical crop development stages, can significantly elevate the risk of some crop diseases. Wet soils in fields of flowering canola are a concern with respect to the development of sclerotinia

IEEE Transactions on Aerospace and Electronic Systems, 1967
The general theory of side-looking synthetic aperture radar systems is developed. A simple circuit-theory model is developed; the geometry of the system determines the nature of the prefilter and the receiver (or processor) is the postfilter. The complex distributed reflectivity density appears as the input, and receiver noise is first considered as ...

Orthogonal Coprime Synthetic Aperture Radar
IEEE Transactions on Geoscience and Remote Sensing, 2017Recently, we have proposed a new synthetic aperture radar (SAR) technique, which we called “Coprime SAR” (CopSAR), applicable to the case of bright targets over a dark background and therefore useful in ocean monitoring for ship detection. The CopSAR technique is based on the adaptation of the coprime array beamforming concept to the case of SAR ...

The Capella Synthetic Aperture Radar Constellation
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018The Capella constellation will consist of 36 agile synthetic aperture radars. Each radar will operate at an altitude of around 500 km in an approximately 90-minute polar orbit, providing average imaging revisit times of less than one hour. The radars will be single-pol X-band systems, capable of operating over a 500 MHz bandwidth in stripmap and ...

On Bistatic Inverse Synthetic Aperture Radar
IEEE Transactions on Aerospace and Electronic Systems, 2007The use of multiple radar configurations can overcome some of the geometrical limitations that exist when obtaining radar images of target using inverse synthetic aperture radar (ISAR) techniques. It is shown here how a particular bistatic configuration can produce three view angles and three ISAR images simultaneously.

Radar is an active microwave remote sensing system, first developed during the Second World War with the purpose of evaluating distances between targets (aircrafts, ships, etc.) and the antenna used to send and receive an Electromagnetic (EM) pulse (Woodhouse 2006; Brown 1999).

Synthetic Aperture Radar Correlation Imaging
SIAM Journal on Imaging Sciences, 2015In synthetic aperture radar (SAR) imaging, a scene of interest is illuminated by electromagnetic waves. The goal is to reconstruct an image of the scene from the measurement of the scattered waves using airborne antenna(s). A new imaging algorithm, known as correlation imaging, is suggested in which an image is formed of the reflectivity function ...

Since its appearance in the nineteen fifties Synthetic Aperture Radar (SAR) has been experiencing a continuous growth in systems, performance and applications. Thanks to its possibility of any-weather and any-time operation, SAR became rapidly a primary remote sensing system for Earth and planetary observation and today a widening of its application in
