SYMEO Local Positioning Radar System Product Family LPR®-1DHP-200 – Product Documentation 1 Safety Notes General The LPR®-1DHP-200 product family is a radar distance measurement sensor that may be used to measure distances between a radar unit and a reflector or between two radar units. LPR®-1DHP-200 radars are purely tracking and assistance systems. They do not satisfy special requirements for personal or functional safety or explosion protection.
SYMEO Local Positioning Radar System Product Family LPR®-1DHP-200 – Product Documentation Transport and Storage Do not drop the device and do not expose it to strong vibrations. Power Supply While installing or using it in open-air, transient overvoltage cannot be excluded. Overvoltage protection is to be used for low voltage in accordance to DIN EN 61643-21 and IEC 61643-21. Be careful that the device can be damaged by reverse polarity despite implementation of polarity reversal protection.
SYMEO Local Positioning Radar System Product Family LPR®-1DHP-200 – 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 Product Family LPR®-1DHP-200 – Product Documentation The LPR®-1DHP-200 Product Family 2 The LPR®-1DHP-200 is a radar distance measurement sensor product family. The product family consists of different product types, which are based on the same hardware platform. Depending on your purchased product type, your radar provides one or more of three different radar modes, namely a primary radar mode, a secondary radar mode and a diversity radar mode. Table 2.
SYMEO Local Positioning Radar System Product Family LPR®-1DHP-200 – Product Documentation 3.2 Radar Beam and Opening Angle The LPR®-1DHP-200 emits a high frequency electromagnetic radio signal with its integrated antenna.

SYMEO Local Positioning Radar System Product Family LPR®-1DHP-200 – Product Documentation 5 Mounting 5.1 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. The radar units and/or corner reflectors must move parallel to the radar beam in the installation.
SYMEO Local Positioning Radar System Product Family LPR®-1DHP-200 – Product Documentation For a primary radar distance measurement, typically a single radar unit and a recommended corner reflector are mounted facing each other. For operation in the primary radar mode the following issues must be considered: The radar and the corner reflector must be installed in a way that the center of the corner reflector is aligned with the center of the radar beam.
SYMEO Local Positioning Radar System Product Family LPR®-1DHP-200 – Product Documentation Follow the subsequent steps for proper installation of the radar units: Mount a standard mounting bracket to one side of the measurement setup. Mount the radar unit into the mounting bracket. Repeat the first two steps on the other side of the measurement setup. Carefully align both radar units to each other. To do so, it is recommended to use a laser level fitted into the alignment aids.
SYMEO Local Positioning Radar System Product Family LPR®-1DHP-200 – Product Documentation Device -> Settings -> Measurement details o Target search mode = “First” if the reflector is the first target in range, “Strongest” if the reflector is the strongest target in range. The setting “Target search mode” highly impacts the behavior of the radar, especially in multi target environments (see Figure 8.16).
SYMEO Local Positioning Radar System Product Family LPR®-1DHP-200 – Product Documentation o Run a warm up phase of 30 minutes before calibration. o Compare the “current distance” to the actual distance in your measurement setup for all ranges. o The mean value of the difference between the actual distance and the measured distance is the reference-offset value, which needs to be added to the current distance to match the radar’s and installation’s coordinate systems.
