Rd-03D is a radar module equipped with Silicon Microelectronics' S5KM312CL chip. S5KM312CL is an integrated microcontroller millimeter wave sensor SoC based on FMCW radar transceiver technology. It operates in the 24 GHz K-band with a maximum sweep bandwidth of 0.25GHz. This module uses FMCW waveform and S5 series chip's proprietary advanced signal processing technology, combined with MCU's proprietary radar signal processing and built-in intelligent positioning and tracking algorithm, to detect multiple targets in a designated area and report the results in real time. Users can quickly Develop corresponding targeting tracking products.
