Wide-angle SAR-matched filter image formation for enhanced detection performance

摘要

In this paper, a simple angle matched image formation algorithm is implemented in which an amplitude weighting corresponding roughly to the dominant feature of a man-made target is used to match its angular response. As such, it represents the first step to a complete frequency-angle matched filter image formation method now under development. Using a common set of measured data, comparisons with practical implementations of two conventional imaging/detection techniques studied previously and a single-pixel detection baseline indicate that only the current approach offers significant performance improvement over baseline.
