Wideband Radar Target Detection Theory in Coherent K Distributed Clutter

The aim of this study is to analyze the influence of neglecting K distributed clutter texture on wideband radar distributed targets detection. At first, the texture and the speckle of K clutter are researched and the Probability Density Function (PDF) of K clutter and its texture are derived, then the optimal detector by Neyman-Pearson (NP) is proposed, by contrast, another detector-Suboptimum ...

Coherent interferometric imaging for synthetic aperture radar

This paper shows that the coherent interferometric imaging strategy originally proposed in the context of passive or active arrays of antennas can be implemented for synthetic aperture radar, in which a single antenna is used as an emitter and as a receiver at successive positions along a trajectory. The idea is to backpropagate the cross correlations of the recorded signals over selected frequ...

Model-Based Radar Power Calculations for Ultra-Wideband (UWB) Synthetic Aperture Radar (SAR)

Design and Development of a Wideband Coherent Radar Depth Sounder

Sea level rise is an important indicator of global climate change. Sea level has been increasing at about 2mm/year over the past century and may continue to do so. The continuing rise in sea level will have a devastating impact on humanity as approximately 60% of people on this planet live in the coastal regions. The polar ice sheets, which account for 80% of earth’s fresh water supply are a ma...

Operational Ship Monitoring System Based on Synthetic Aperture Radar Processing

This paper presents a Ship Monitoring System (SIMONS) working with Synthetic Aperture Radar (SAR) images. It is able to infer ship detection and classification information, and merge the results with other input channels, such as polls from the Automatic Identification System (AIS). Two main stages can be identified, namely: SAR processing and data dissemination. The former has three independen...
