1. A system for signal detection in an electromagnetic environment, comprising:
at least one receiver, at least one processor, and at least one memory;
wherein the system is operable to create power level measurements of the electromagnetic environment;
wherein the system is operable to perform anomaly detection and alarm generation using a machine learning (ML) algorithm;
wherein the system is operable to determine a baseline;
wherein the system is operable to reveal at least one signal based on the baseline to create signal data;
wherein the system is operable to use a sensitivity parameter to set an energy threshold that determines if the at least one signal is a signal of interest;
wherein the sensitivity parameter is optimized by an event compositor that processes real-time events from the system and records signal observations;
wherein the at least one processor is operable to use a first smoothing filter and a second smoothing filter to create a calibration vector;
wherein the second smoothing filter is performed only on frequencies outside a frequency range of the at least one signal;
wherein the at least one processor is operable to use the calibration vector to de-bias the signal data;
wherein the system is operable to calculate signal degradation data for the at least one signal based at least in part on noise figure parameters, hardware parameters, and environmental parameters;
wherein the hardware parameters comprise antenna position, antenna type, orientation, and/or effective isotropic radiated power (EIRP);
wherein the system is operable to process the signal data using compressed data for deltas;
wherein the deltas are differentials from the baseline and minimize data sets or sample data required for comparisons and/or analytics; and
wherein the system is operable to reconstruct the at least one signal using the deltas and the baseline.
