Various embodiments are directed to a radar reflector configured for radar-based distance measurements for determining a position of an elevator car within an elevator shaft. The radar reflector comprises three or more triangular panels defining a pyramidal frustum volume having a base plane and an upper plane that are parallel. The pyramidal frustum volume is configured to directly reflect radar signals originating from a radar transceiver back to the radar transceiver based at least in part on the triangular panels being mutually perpendicular at a projected apex above the upper plane. The reflected radar signals reflected by the radar reflector have substantially parallel trajectories with the original, pre-reflected radar signals emitted by the radar transceiver. The triangular panels of the radar reflector being mutually perpendicular advantageously maintains direct reflection of radar signals in spite of any potential horizontal tilt of the radar reflector to a certain extent.
