Abstract
A method for detecting tonal interference in phase shift keyed signal modulations includes feeding a phase shift keyed signal with an error signal through a lock loop from a phase lock loop. The lock loop feeds the phase shift keyed signal with an error signal through a lock counter that counts a time for the error signal to measure a voltage below a minimum threshold. An enable signal is sent via the lock counter to the frequency channelizer module when the voltage drops below the minimum threshold. The frequency channelizer module splits a spectral content of the phase shift keyed signal into frequency channels. An output of the frequency channels is sent via the frequency channelizer module to a spectral anomaly processor. An automated test is performed with the spectral anomaly processor for each frequency channel, thereby determining a frequency or phase band of the tonal interference.
