Abstract

An active protection system comprising an ultra wideband (UWB) 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. In a further embodiment, an antenna array is steered by using subarray groups having fixed timing within the group and variable timing from group to group.
