SYMEO Local Positioning Radar System ® -1DHP-350 – Product Documentation Exposure Requirements To satisfy FCC exposure requirements a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during operation. To ensure compliance, operations at closer distances than this are not recommended.
SYMEO Local Positioning Radar System ® -1DHP-350 – Product Documentation The LPR -1DHP-350 ® The LPR -1DHP-350 radar system performs 1D distance measurements for short and ® medium ranges with high accuracy. By means of primary radar or secondary radar...
SYMEO Local Positioning Radar System ® -1DHP-350 – Product Documentation Radar Beam and Field of View (FoV) The LPR -1DHP-350 emits a high frequency electromagnetic radio signal with its integrated ® antenna. The EM-wave is focused by a dielectric lens and creates a radar beam with an FoV (half power beam width, HPBW) of +/-2,5°.

SYMEO Local Positioning Radar System ® -1DHP-350 – Product Documentation Mounting General Mounting Instructions Site-specific mounting instructions must be followed if available. The more accurately the radar units and reflectors are aligned to each other, the better the performance of the measurement setup will be in terms of accuracy and range.
SYMEO Local Positioning Radar System ® -1DHP-350 – Product Documentation Radar and radar reflector must be aligned to each other with maximum accuracy (at least +/- 2.5°). Minimum horizontal and vertical offset between radar and reflector must be ensured.
