RF-based material identification systems and methods

A system for identifying detected materials, the system comprising:

• a material database that stores:
• respective associations of a plurality of materials with a corresponding resonance frequency, and
• a priority for detecting each material from a subset of the materials that are associated with an application;
• a radio frequency (RF) transmitter that transmits an RF signal at a first resonance frequency into an environment, the first resonance frequency corresponding to at least one material from the subset of the materials in order of the priority for the application in accordance with the material database;
• an RF receiver that receives a response signal from the environment, the response signal corresponding to the transmitted RF signal at the first resonance frequency;
• a processor that executes instructions from memory, wherein the processor executes the instructions to:
• analyze the response signal for resonance characteristics that indicate a presence of the at least one material in the environment, and
• calculate a mass of the at least one material based on an amplitude of the response signal and a distance between the RF transmitter and the at least one material in the environment;
• and
• a display device that displays a graphic interface reflecting:
• the presence of each material in the environment as indicated by the resonance characteristics, and
• the corresponding mass of each present material.
