Fujitsu Components America, Inc. has introduced a 3-channel, 24GHz Doppler radar sensor with a wide speed-detection range and high interference tolerance. The module and evaluation kit facilitates the rapid development and evaluation of various non-contact, movement sensing products even without high-frequency RF electronics expertise. Target applications include human vital sign and fall monitoring, structural and mechanical movement detection, machine maintenance, and more, for the healthcare and industrial markets.

The FWM7RAZ01 supports IF (I/Q) output signals from 1Hz to 1 MHz enabling it to wirelessly detect movement speeds from 6 mm per second to 6 km per second, within a 30-meter range. Although 1 MHz of Doppler Effect is not observable in real-world applications, it is effective for detecting signal interference. To prevent signal overlap, the system can select a different channel and avoid misdetection before it happens.
