1. An apparatus for signal detection in an electromagnetic environment, comprising:
at least one receiver, at least one processor, and at least one memory;
wherein the apparatus is operable to create power level measurements of the electromagnetic environment;
wherein the apparatus is operable to determine a baseline;
wherein the apparatus is operable to reveal at least one signal based on the baseline to create signal data;
wherein the apparatus is operable to use a calibration vector to de-bias raw signal data;
wherein the apparatus is operable to determine if the at least one signal is moving using a frequency-locked loop by determining if there is a Doppler change in the at least one signal;
wherein the apparatus is operable to calculate a first derivative of the power level measurements and a second derivative of the power level measurements;
wherein the apparatus is operable to select most prominent derivatives of the first derivative and the second derivative;
wherein the apparatus is operable to perform a squaring function on the most prominent derivatives;
wherein the apparatus is operable to create impressions of the electromagnetic environment based on a machine learning algorithm;
wherein the apparatus is operable to process the signal data using compressed data for deltas;
wherein the apparatus is operable to reconstruct the at least one signal using the deltas and the baseline;
wherein the apparatus is operable to fill gaps during reconstruction of the at least one signal where data of the at least one signal is absent; and
wherein the apparatus is operable to produce a topographic map displaying propagation of spectral power per frequency band.
