WebRADAR is a system that uses radio waves to determine and map the location, direction, and/or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations and terrain. A transmitter emits radio waves, which are reflected by the target and detected by a receiver, typically in the same location as the transmitter. Web17 apr. 2024 · MTI radar is a long-range, low pulse repetition frequency (PRF) radar used to detect and track small (~2 m 2) moving targets at long distances (up to ~30 km) by eliminating ground clutter (aka chaff). MTI is useful when velocity is not a big concern (i.e. “just tell me if something is moving”).

Web11 apr. 2024 · As the name suggests, software-defined radios are RF components that were developed to shift the radio processing paradigm from the analog domain to the digital domain.
