UWB Sensor Web Based Phased Array

"The military is rapidly developing an information centric focus, and based partly on the projected capabilities of radios, sensor nets, and communication technology in general, is defining many next-generation systems, such as Future Combat Systems. A UWBsensor net, which has (in addition to accurate ranging between nodes) tight synchronization in time, provides revolutionary agility offers N2 improvements in radio and radar power. The key innovation in the proposed work is the ability to achieve ad hocnetworks where neighboring network nodes are able to create ad hoc phased arrays for radar imaging and directional transmission. This corresponds to optimal use of all sensors cooperatively for both radar imaging (target detection) and communication ofinformation among sensors, and from the network to a remote point outside. The power transmitted at the focus point is proportional to N2 where N is the number of nodes so there are very significant gains to be achieved over transmission from a singleunit. This capability is revolutionary and will have revolutionary benefits in terms of range, power savings watts at the receiver), radar imaging resolution, and covertness. In addition, we propose a novel method to obtain accurate range measurements,even when no Line Of Sight (LOS) exists. Phased Array capability for networks of radio and radar units will deliver much increased sensitivity and ability to relay data from the battlefield. Besides military applications, national border and governmentfacility security will be major markets for this new technology."
