SUMMARY Home security sensors are becoming more and more practical today for protection against intruders, and several sensor types, such as infrared, video cameras, and microwave radio are commonly used. Ultra‐wideband impulse‐radio (UWB‐IR) sensors have lately attracted considerable attention because they are expected to measure not only the motion of an intruder but also the distance. This paper presents an indoor intruder detection sensor system using stepped FM based on UWB radio which can detect and track the movement of an intruder. The usefulness of the method is experimentally investigated using our fabricated sensor. The measurements were conducted for various intrusion scenarios inside a typical house.
