TL;DR: An experimental bistatic radar system is described that detects and tracks targets to ranges in excess of 150 km from the receiver, using echoes from a non-cooperative FM radio transmitter.
Abstract: An experimental bistatic radar system is described that detects and tracks targets to ranges in excess of 150 km from the receiver, using echoes from a non-cooperative FM radio transmitter The system concept and limitations on performance are described, followed by details of the processing used to implement the system An adaptive filter algorithm is described that is used to efficiently remove interference and strong clutter signals from the receiver channels A computationally efficient algorithm for target detection using Doppler-sensitive cross-correlation techniques is described A simple constant false alarm rate algorithm for target detection is described, together with a description of a Kalman filter based target association algorithm Representative results from the system are provided and compared to truth data derived from air traffic control data

TL;DR: In this article, the state-of-the-art multispectral pansharpening techniques for hyperspectral data were compared with some of the state of the art methods for multi-spectral panchambering.
Abstract: Pansharpening aims at fusing a panchromatic image with a multispectral one, to generate an image with the high spatial resolution of the former and the high spectral resolution of the latter. In the last decade, many algorithms have been presented in the literatures for pansharpening using multispectral data. With the increasing availability of hyperspectral systems, these methods are now being adapted to hyperspectral images. In this work, we compare new pansharpening techniques designed for hyperspectral data with some of the state-of-the-art methods for multispectral pansharpening, which have been adapted for hyperspectral data. Eleven methods from different classes (component substitution, multiresolution analysis, hybrid, Bayesian and matrix factorization) are analyzed. These methods are applied to three datasets and their effectiveness and robustness are evaluated with widely used performance indicators. In addition, all the pansharpening techniques considered in this paper have been implemented in a MATLAB toolbox that is made available to the community.
