The LD2450 is a motion target tracking sensor module of the Hilink 24G millimeter wave radar series, which features highly simplified 24GHz radar sensor hardware and intelligent algorithm firmware. The solution is mainly used in general indoor scenarios such as homes, offices, and hotels to enable location tracking of moving human bodies. Moving target tracking is to track the position of the moving target in the region in real time and realize the measurement of the distance, angle, and speed of the moving target in the region. The sensor hardware consists of an AloT millimeter wave radar chip, a high-performance single-transmitter and dual-receiver microstrip antenna, and a low-cost MCU and peripheral auxiliary circuits. The intelligent algorithm firmware uses FMCW waveforms and advanced signal processing technology proprietary to the radar chip. It supports serial output of detection data, which is plug-and-play and can be flexibly applied to various intelligent scenarios and end
