Abstract
A method includes extracting a first detection entry from a target database, the first detection entry including a first identifier of a first RF detection device, wherein the first RF detection device is located at a first side of a perimeter; determining a second RF detection device located at a second side of the perimeter; searching for a second detection entry associated with the second RF detection device; and, if the first detection entry and the second detection entry both include detection data that indicates the presence of a target material, storing an indication that the target material is within the perimeter; otherwise, store an indication that the target material is outside of the perimeter.
Claims23
A system for networked RF-based material detection, the system comprising:
- a plurality of RF detection devices positioned along a perimeter of a defined area and including at least a first RF detection device located at a first side of the perimeter, the first RF detection device comprising:
- an interface configured to access a material database associating each of a plurality of materials with one or more corresponding resonance frequencies;
- an RF transmitter that transmits an RF signal at a resonance frequency into an environment for each material in at least a set of the materials;
- an RF receiver that receives a response signal from the environment for each RF signal;
- and
- one or more processors that execute instructions stored in memory, wherein the processor executes the instructions to:
- analyze the response signal for resonance characteristics that indicate a presence of at least one of the materials in the set,
- generate a first detection entry to store in a target database, the first detection entry including at least an identifier of the first RF detection device that received the response signal and detection data,
- determine that at least one other detection entry associated with at least one other of the RF detection devices located at a second side of the perimeter also includes detection data that indicates the presence of the at least one material, and
- store an indication that the at least one material is within the perimeter based on the first detection entry and the at least one other detection entry.
