Abstract: Systems and methods for processing radiofrequency signals using modulation duty cycle scaling. One system includes a first receive path configured to directly sample a first signal in a first frequency range. The system includes a second receive path configured to convert a second signal in a second frequency range. The second receive path includes a receive modulator operating over a duty cycle. The receive modulator is configured to adjust the duty cycle by a predetermined scaling factor.

Abstract: A communication system and method are provided to conduct waterway searches for the detection and identification of objects and the generation of law enforcement agency alerts and pre-approved external agency notifications. A water body surveillance apparatus, under control of a law enforcement agency, surveys above and below a water surface to detect objects and collect data pertaining to the detected objects. The communication system identifies the detected object and generates an alert to the law enforcement agency identifying the object. A notification is sent to pre-approved external agencies based on object type. The pre-approved external agencies may include other law enforcement agencies different from the law enforcement agency and non-law enforcement agencies, such as pre-approved insurance agencies, and vehicle repossession companies, environmental agencies.
