Product Outline MS-RA1xM radar modules are the motion sensors that detect motion and speed of objects. As Doppler radar sensor modules, they operate in the 24 GHz ISM band. The RA1xM series can be categorized into three product groups—MS-RA11M, MS-RA12M, and MS- RA14M—in accordance with a number of their antennas. Table 1 introduces operating ranges of three product groups, which are based on an RCS1 [1m²] (targeting an adult). Table 1. Operating Ranges of Three Product Groups Product group Operating ranges MS-RA11M 5 to 8 m MS-RA12M 7 to 10 m MS-RA14M 9 to 12 m The range introduced in the table 1 can be adjusted by the operating environment and the gain of the digital amplifier embedded in the module. Since the MS-RA1xM module includes an exclusive transceiver for one-chip radars and an MCU for 32-bit signal processing, it has outstanding performance and provides various functions through digital signal processing. As a one-chip device, the radar IC has almost no margin of error even at a high frequency of 24 GHz and adjusts the temperature to match the external environment with a temperature compensation circuit embedded in the IC. Features such as the digital amplifier, FFT signal processor, and signal comparator can be implemented by using the embedded 32-bit Cortex M0+ MCU, and the functions including fine tuning of detection range (50 stages), configuration of object speed (km/h), configuration of range of 2-stage proximity detection, and prevention of error caused by vibration are …

The turntable shall rotate 360 degrees to determine the position of maximum emission level. EUT is set far-field distance away from the receiving antenna, which varied from 1 m to 4 m to find out the highest emission. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. In order to find out the max. emission, the relative positions of this hand-held transmitter (EUT) was rotated through three orthogonal axes according to the requirements in Section 8 of ANSI C63.10. (Version: 2013) 2.4 DESCRIPTION OF TEST MODES The EUT has been tested under operating condition. Test program used to control the EUT for staying in continuous transmitting and receiving mode is programmed. Report No. HCT-RF-2002-FC023 Page 7 of 26 3.
