Abstract

Embodiments relate to a RF localization system that determines the position of a RF source of interest (RFSOI) relative to the RFLS. The RFLS includes man-portable nodes that communicate via a self-organizing WAN. Each node includes a communications device conductively coupled to antenna elements oriented in each nodal cardinal direction and battery each communicatively coupled to a control circuit(s). The control circuit is configured to: establish the WAN; capture RSSI values for each antenna element; determine the position of the RFSOI relative to the node; when not functioning as a primary node, transmit the determined position to a primary node or a computing device that's external to the WAN for processing; and when functioning as a primary node, determine the relative position of the RFSOI relative to the plurality of nodes using the received determined position. The primary node determines the position of the RFSOI relative to the nodes.
