Hailingke 24G human motion tracking trajectory radar module LD2453: one transmission, two receptions, multi-target tracking--EngrWorld

Target tracking refers to real-time tracking of the target's position within an area, enabling distance measurement, angle measurement, and speed measurement of the target.

HLK-LD2453 is a high-precision multi-target recognition sensor. This solution is mainly applied in ordinary indoor scenarios such as homes, offices, and hotels to achieve positioning and tracking of multiple human bodies.

The sensor hardware consists of an AIoT millimeter-wave radar chip, a high-performance one-transmit two-receive microstrip antenna, a low-cost MCU, and peripheral auxiliary circuits. The intelligent algorithm firmware adopts FMCW waveform and advanced signal processing technology proprietary to the millimeter-wave radar chip.

The main features of the HLK-LD2453 sensor are as follows:

 24 GHz ISM frequency band

 Integrates intelligent millimeter-wave radar single chip and intelligent algorithm firmware

 Accurate target positioning and tracking

 Ultra-small module size

 HLK-LD2453 dimensions: 7mm X 30mm

 Ambient temperature: -20℃ ~ 70℃

 3.3 V power supply

 Maximum detection range: 6 m

 Azimuth angle ±40°, elevation angle ±30°

 Wall-mounted installation

 Maximum detection of 3 targets

The HLK-LD2453 multi-target recognition sensor can accurately locate and track human targets, and is widely used in various AIoT scenarios, including the following types:

 Smart home

Perceive the distance and angle of the human body, and report the detection results for the main control module to intelligently control the operation of home appliances such as air conditioners and fans;

 Smart business

Position sensing, identify the approach or departure of the human body within the set position range, and turn on or off the screen in a timely manner;

 Bathroom

Smart toilets accurately control the automatic opening and closing of the toilet lid;

 Smart lighting

Identify and perceive the human body, with precise position detection, which can be used in home lighting equipment (induction lights, desk lamps, etc.).
