Provided is a simultaneous radio detection and bearing system (100). More specifically, the radio detection and bearing system (100) includes an RF conditioning subsystem (152) having a plurality of First Frequency Range and Second Frequency Range signal receiving channels. The RF conditioning subsystem (152) operable to combine First Frequency Range and Second Frequency Range signals as a first internal data stream (304). A coherent multi-channel digitizer subsystem (154) is coupled to the RF conditioning system (152), the coherent multi-channel digitizer subsystem (154) operable to generate a time domain snapshot (600) of the first internal data stream (304). An audio recording subsystem (156) is also coupled to the RF conditioning subsystem (152). A processor (158) is coupled to the coherent multi-channel digitizer subsystem (154) and the audio recording subsystem (156). The processor (158) is operable to transform the time domain snapshot (600) to a frequency spectrum (604) and identify at least one signal (608) above a threshold (606) at a determined frequency, determine the bearing (908) of the signal (608), and provide the determined frequency to the audio recording subsystem (156). The audio subsystem (156) contemporaneously records the signal (608) upon the determined frequency. An associated method (500) of radio detection and bearing determination is also provided. |
