Abstract
Provided is a non-transitory machine readable medium on which is stored a computer program including instructions to adapt a computer system having at least one processor as a simultaneous radio detection and bearing system, including: an RF conditioning subsystem for connection to a plurality of arrays of Frequency Range signal receiving channels, the RF conditioning subsystem operable to combine the signals from the arrays as a first internal data stream; and a coherent multi-channel digitizer subsystem coupled to the RF conditioning system, the coherent multi-channel digitizer subsystem operable to generate a time domain snapshot of the first internal data stream. The computer instructions further adapting the processor to transform the time domain snapshot to a frequency spectrum and identify at least one signal above a threshold at a determined frequency, determine the bearing of the signal, and provide the determined frequency of a selected identified signal to an audio recording subsystem, the audio subsystem contemporaneously recording the selected signal upon the determined frequency.
