In this Chapter, we propose a novel dynamic monopulse radar (DMR) sensor with new localizing algorithm for both indoor positioning and surgical instrument positioning. The proposed DMR system consists of a steerable comparator, RSSI modules, and a microcontrol unit (MCU). Based on the engagement between radar techniques and phased array techniques, this proposed system can provide two-dimensional (2-D) angulation positioning using only a single positioning node.
