System and method for active protection of a resource
First Claim
1. A method for active protection of a resource comprising the steps:
- providing an ultra-wideband (UWB) radar;
using said UWB radar to search for a threat, said threat being a moving object;
determining a first location of said threat by combining scans of said UWB radar according to a candidate trajectory;
providing an optical search device;
determining a second location of said threat using said optical search device, said second location being determined based on said first location;
imparting damage to said threat based on said second location of said threat.

Abstract
An active protection system comprising an ultrawideband radar for threat detection, an optical tracker for precision threat position measurement, and a high powered laser for threat kill or mitigation. The uwb radar may use a sparse array antenna and may also utilize Doppler radar information. The high powered laser may be of the optically pumped solid state type and in one embodiment may share optics with the optical tracker. In one embodiment, the UWB radar is used to focus the high power laser. Alternative interceptor type kill mechanisms are disclosed. In a further embodiment, the kill mechanism may be directed to the source of the threat.
