Abstract:
A Multiple Protocol Signal Detector, MPSD (320, 500) has a mixer (406) that receives signal energy from a multi-band antenna system (324) via a low noise amplifier (402) and from a variable frequency synthesizer (408) via a first variable band pass filter (410). The output of the mixer (406) passes through a second variable band pass filter (416) to an envelope detector (418) a power detector (419) and a low resolution A/D (420) that inputs digitized samples to a binary modulation detector, BMD (422). A controller (424) configures the aforementioned devices of the MPSD (320) to detect communications using different protocols based on a scan Look Up Table (426).
