1. A system for automatic signal detection in a radio-frequency (RF) environment, comprising:
a multiplicity of sensor devices configured for communication in a network;
wherein the multiplicity of sensor devices comprises at least one RF receiver, a generator engine, and an analyzer engine;
wherein the at least one RF receiver is configured to measure power levels in the RF environment and generate fast Fourier transform (FFT) data based on power level data;
wherein the generator engine is configured to calculate a power distribution by frequency of the RF environment, including a first derivative of the FFT data; and
wherein the analyzer engine is configured to create a baseline of the RF environment, identify at least one conflict situation by comparing the power distribution to the baseline of the RF environment, and identify at least one signal based on the first derivative of the FFT data in the at least one conflict situation.
