Detection and Mitigation of Strong Azimuth Ambiguities in High Resolution SAR Images [PDF]
, 2016 Azimuth ambiguities of bright point-like targets become more pronounced in case of high resolution SAR imaging. When improving the spatial resolution, the compression gain in SAR image formation becomes larger, which increases the dynamic range of SAR ...

WAH‐i: Optimising microphone array geometry for customised localisation accuracy
Methods in Ecology and Evolution, EarlyView.Abstract Accurate spatial localisation of free‐flying echolocating bats is foundational for resolving fine‐scale flight and echolocation behaviour, prey interception and spatial decision‐making in natural environments. Acoustic localisation using microphone arrays is widely employed for this purpose, yet array geometries in field studies are typically ...

IEEE Access, 2018 We analyzed the relation between two opposite effects of mutual coupling (MC), correlation reduction and gain loss, on the MIMO antenna performance in three-dimensional (3D) space. In the antenna level, those MC effects can be represented in terms of two

Methods in Ecology and Evolution, EarlyView.Abstract Observations of three‐dimensional (3D) coarse root system architecture remain limited because most measurement approaches require excavation. Here, we combined dense single‐ and multi‐channel 500 MHz ground‐penetrating radar (GPR) surveys with a flow‐guided connectivity framework to non‐destructively characterise the coarse root architecture ...

Effect of ambiguities on SAR picture quality [PDF]
, 1978 The degradation of picture quality is studied for a high-resolution, large-swath SAR mapping system subjected to speckle, additive white Gaussian noise, and range and azimuthal ambiguities occurring because of the non-finite antenna pattern produced by a
