Provided is a simultaneous radio detection and bearing system. More specifically, the radio detection and bearing system includes an RF conditioning subsystem having a plurality of First Frequency Range and Second Frequency Range signal receiving channels. The RF conditioning subsystem operable to combine First Frequency Range and Second Frequency Range signals as a first internal data stream. A coherent multi-channel digitizer subsystem is 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. An audio recording subsystem is also coupled to the RF conditioning subsystem. A processor is coupled to the coherent multi-channel digitizer subsystem and the audio recording subsystem. The processor is operable 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 to the audio recording subsystem. The audio subsystem contemporaneously records the signal upon the determined frequency. An associated method of radio detection and bearing determination is also provided. |
