Frequency Modulation Detection Systems, Devices, and Methods
Systems, devices, and methods for detecting frequency modulation information are disclosed. For example, these systems, devices, and methods are used for detecting phase-shift keying (PSK) information, linear frequency modulation (LFM) information, and signal source direction. In some embodiments, the method comprises receiving a first signal, receiving a second signal, which is a delayed version of the first signal, mixing the first signal and the second signal to generate a mixed signal, and determining, based on the mixed signal, one or more of the PSK information, the LFM in formation, and the signal source direction.
