REAL-TIME, TWO DIMENSIONAL (2-D) TRACKING OF FIRST RESPONDERS WITH IDENTIFICATION INSIDE PREMISES
First Claim
1. A system comprising:
- a plurality of wearable communicator units, each wearable communicator unit including;
an active tag for identifying and precisely locating the wearable communicator unit; and
a display; and
a plurality of 2-D sensor units that;
operate first in a static mode that gathers information to depict a layout of a field of operations;
then operate in a dynamic mode that searches for motion of a subject and reads an active tag of each wearable communicator unit for locating a precise position of each wearable communicator unit; and
whereineach wearable communicator unit displays the layout depiction, and subject and communicator location information on a display of the wearable communicator unit.

Abstract
A combination of active reader tags and ultra wideband (UWB) radar systems provide real-time monitoring of first responders, with identification of each team member using active tags, and detection of victims or other subjects using motion or breathing detection, in a field of operations such as a building affected by fire or hazardous material or search and rescue mission area. Initially, a cluster of miniaturized radars (sensors) act in a static mode of operation, gathering static radar information used to depict a constructed layout of the premises. The cluster of radars then operate in a dynamic mode that detects motion or breathing of multiple subjects inside the field of operations. With dual mode operation the system can read the active tags identification, and by triangulation, display the position of each first responder with its identification and positions of subjects on a composite image of the constructed layout.
