1. A system for signal detection or conflict detection in an electromagnetic environment, comprising:
at least one electromagnetic receiver configured to measure activity in the electromagnetic environment;
an analyzer engine; and
an event manager;
wherein the at least one electromagnetic receiver is configured to generate fast Fourier transform (FFT) data and I/Q data based on the measured activity in the electromagnetic environment;
wherein the analyzer engine is operable to compare the FFT data to at least one baseline to identify at least one conflict;
wherein the event manager is operable to use parameters of the at least one conflict to determine a course of action, wherein the course of action comprises creating an alarm, storing the I/Q data, and performing direction finding (DF);
wherein the analyzer engine is configured to detect a change in power distribution in the electromagnetic environment based on the FFT data;
wherein the analyzer engine is operable to create the at least one baseline based on calculations of power levels of the measured activity over a predetermined period of time; and
wherein the analyzer engine is configured to detect at least one signal associated with at least one drone based on a first derivative and a second derivative of the FFT data.
