ABSTRACT:
An ultra wideband radar system for detecting moving objects comprising an antenna, which may be scanned in at least one dimension, and a signal processor wherein the signal processor includes a scan combiner that combines scan information in accordance with a candidate trajectory for the moving object. Scans may be combined by integration or filtering. A fast calculation method is described wherein the scans are combined into subsets and subsets are shifted in accordance with the candidate trajectory before further combination. A method is described wherein a region is scanned with an ultra wideband radar, the scan information is combined in accordance with an expected trajectory to enhance the object signal to noise. Further features are described wherein the scan information is combined according to a family of trajectories. A trajectory yielding a potential object detection initiates a further scan combination step wherein the family of trajectories is further resolved.
