IR-UWB (Impulse Radio Ultra-Wideband) radar is a short-range, high-resolution sensing technology that transmits extremely short electromagnetic pulses across a wide frequency spectrum to detect and localize objects, people, or movements without requiring subjects to carry any device. Its ability to penetrate non-metallic materials, operate with low power consumption, and provide fine-grained spatial and temporal information makes it particularly valuable for non-intrusive occupancy detection and crowd density estimation in smart buildings and public transportation environments. Key variants differ primarily in antenna configurations, pulse repetition frequencies, and signal processing backends, with some systems supporting multi-node deployments to extend spatial coverage across larger or more complex sensing areas.
