1. An apparatus for signal detection or conflict detection in an electromagnetic environment, comprising:
an analyzer engine configured to generate fast Fourier transform (FFT) data based on measured power levels of at least one signal in the electromagnetic environment;
a generator engine configured to perform a power bin occurrence (PBO) process and generate PBO data based on the measured power levels of the at least one signal;
wherein the generator engine is operable to generate power distribution by frequency over time (PDFT) data and second order power bin occurrence (SOPBO) data based on the PBO data;
wherein the SOPBO data is a 3-Dimensional (3D) array of multiple 2-Dimensional (2D) histograms presenting the PBO data;
wherein the analyzer engine is operable to create at least one mask based on the FFT data;
wherein the at least one mask includes a time period and/or frequency range set by a user;
wherein the analyzer engine is operable to compare the FFT data to the at least one mask to identify at least one conflict and/or the at least one signal;
wherein the analyzer engine is configured to use at least one machine learning algorithm to learn and update signal detection parameters; and
wherein the analyzer engine is configured to calculate a SOPBO baseline based on the SOPBO data.
