Multipath Reflectivity Estimation in Urban Environments for Synthetic Aperture Radar Images [PDF]
Synthetic Aperture Radar (SAR) images a target region reflectivity function in the multi-dimensional spatial domain of range and cross-range. SAR synthesizes a large aperture radar in order to achieve a finer azimuth resolution than the one provided by ...

Lucky imaging and aperture synthesis with low-redundancy apertures [PDF]
Lucky imaging, used with some success in astronomical and even horizontal-path imaging, relies on fleeting conditions of the atmosphere that allow momentary improvements in image quality, at least in portions of an image.

An Investigation on the Damping Ratio of Marine Oil Slicks in Synthetic Aperture Radar Imagery
The damping ratio has recently been used to indicate the relative internal oil thickness within oil slicks observed in synthetic aperture radar (SAR) imagery. However, there exists no well-defined and evaluated methodology for calculating the damping ratio.

Extending AMCW lidar depth-of-field using a coded aperture [PDF]
By augmenting a high resolution full-field Amplitude Modulated Continuous Wave lidar system with a coded aperture, we show that depth-of-field can be extended using explicit, albeit blurred, range data to determine PSF scale. Because complex domain range-

Investigation of the equivalent circuit parameters and design of a dual polarised dual frequency aperture coupled microstrip antenna [PDF]
This paper presents a simplified approach to the design of a single feed dual polarised, dual frequency (1.9 and 2.4 GHz) aperture coupled microstrip antenna. Using simulation and practical investigation, the coupling between the microstrip feed line and
