MR60BHA1 4. Main operating properties 4.1 Radar module operating range The radar module beam coverage is shown. The radar coverage is a threedimensional sector of 80° horizontally and 80° tilted. Due to the radar beam characteristics, the radar has a relatively long range in the direction normal to the antenna face, but a shorter range if it deviates from the antenna normal.

MR60BHA1 Fig. 5 Schematic diagram of the ceiling mount (2) Tilt mounting With tilt mounting, the radar is fixed to a wall or bedside, the radar is mounted at an angle (as shown in Fig. 6) and the radar beam is directed at the body at an angle, with the centre of the radar beam corresponding to the position of the human chest cavity. In this installation mode, the radial distance between the radar and the body to be measured is ≤ 2 m. Fig.
MR60BHA1 (3) Horizontal installation The radar is placed horizontally (as shown in Fig. 7), the radar is fixed to a wall or placed on a table, the radar beam is directed towards the human body and the centre of the radar beam corresponds to the position of the human thorax. The distance between the radar and the human body to be measured in this installation mode is ≤ 2 m. Fig. 7 Horizontal installation diagram Fig.
