MS- RA1xM Radar Module

MS-RA1xM Datasheet

Features

 A radar module operating in K-Band of 24.05GHz–24.25GHz

 Motion and speed detection available both for indoor and outdoor use

 Product groups with various detection ranges between 5 m and 15 m (detection range is based on

human motion, and the maximum range may be adjusted using the embedded digital amplifier and

gain controller)

 PCB patch antenna with various operating ranges

 Small (22 x 18 mm/22 x 22.5 mm/33 x 32 mm) and low-power module (60 mA)

 Embedded 32-bit digital signal processing function

— 8-stage digital amplifier

— 30-stage gain controller

— Adjustment of detection range, and detection of micro motion (240-stage fine tuning achieved

by a combination of 8-stage digital amplifier and 30-stage gain controller)

— Detection of object speed (km/h) using 256 FFT

— Min/max speed detection

— 2-stage proximity detection

— Vibration error detection

 Evaluation board and GUI software for simple evaluation of module operations and easy application

development

 SDK for development of dedicated software (including signal processing library)

 Temperature compensation circuit maintaining operational features even with changes in

environmental conditions

 Embedded protection filter (2.4 GHz Wi-Fi noise immunity) to prevent interference from surrounding

noises, especially communication noises

 The most common single power source, 3.3 V power supply operates the device.

 Same interface pins used for all modules to ensure compatibility.
