Patent ID: 7920088

Claim:
A method that uses ultra-wideband RF energy to detect objects of interest that comprises in combination; (a) transmitting repetitive bursts of ultra-wideband RF impulses in the direction of a target area to search for objects of interest, (b) receiving and amplifying signals that are reflected from objects of interest and background clutter in the target area, (c) converting the said received and amplified signals into digital form, (d) performing signal processing functions on said converted signals to reduce noise in the digitized data, (e) incrementally analyzing each said signal processed radar return with a windowing function wherein said window function is moved and performed across the entirety of each processed radar return, (f) calculating any plurality of domain parameters from each said windowing function and using calculated values to extract target specific feature information that distinguishes objects of interest from background clutter, (g) outputting said target feature information into an automatic target recognition method that distinguishes objects of interest from background clutter in the feature information, (h) reporting object class output from said automatic target recognition method to a display device.
