We consider a multi-static radar where the transmitted signal is reflected from scatterers on the ground and received by multiple widely spaced sensors. Conventional geolocation algorithms are based on variants of the maximum likelihood estimator optimized for a single reflector. These algorithms have a natural resolution limit determined by the time-bandwidth product of the signal and the sensor-reflector...
Consider data collected by two types of sensors with disparate capabilities. A technique is presented for constructing a high quality image from an image measured by a low quality sensor, given training sets of high quality and low quality images of related scenes. The method involves calculation of a non-linear transformation using the training data. The transformation is then applied to the low...
