A range gate in radar refers to a specific segment or window during which the radar system actively listens for return signals. It corresponds to a certain range of distance from the radar transmitter, generally defined by the time it takes for a radar pulse to travel to a target and back. Range gates are essential for isolating and identifying radar yields from different distances, allowing the radar to discern multiple targets at different distances simultaneously.
The range of a gate in radar refers to the specific interval or distance segment that a range gate covers. It is usually defined by the parameters and settings of the radar system, such as pulse repetition frequency (PRF), pulse duration, and signal processing capabilities. Range gates are often set at regular intervals along the range axis to cover the full range of interest that the radar is designed to monitor.
Range gate in radar involves the process of selectively accepting radar yields only from a specific range or distance interval, corresponding to a range gate. This technique allows radar systems to filter out unwanted signals and background clutter, focusing instead on echoes from targets within designated range gates. The range sleeve is crucial to improving radar performance by improving target detection, tracking accuracy and reducing the impact of noise and interference.
A range bin in radar refers to a discrete segment or cell within a range gate that represents a specific range interval. Range bins are used to digitize the radar’s detection capabilities, allowing it to measure and process radar yields of individual spatial increments along the range axis. Each range bin typically corresponds to a small distance increment, allowing radar systems to create detailed profiles of detected targets based on their distance from the radar transmitter.
