Source separation is a critical early processing stage in electronic surveillance systems where the multiple simultaneously intercepted transmissions need to be detected, separated and identified for possible threats (e.g. pulsed and continuous wave radar, navigation systems, etc.). When the signals to be detected and separated overlap in time and frequency this can prove a challenging signal processing task that cannot be solved through simple filtering or beamforming.
