Description

The RD2200 detector is a compact pole-mounted radar detector, operating in the microwave band. It detects the presence of objects and measures traffic parameters in multiple independent lanes. Up to eight user-defined detection zones (lanes) up to 60 m away can be processed simultaneously. Thus, a single RD2200 detector can replace several inductive loop detectors.

The RD2200 unit detects stationary as well as fast moving vehicles, providing presence, traffic volume, occupancy, speed and classification information (car-similar and lorry-similar vehicles).
The information is forwarded to the control units (e.g. input/output concentrator) or via RS232 resp. RS485 serial port to central computer systems.

The detector is uniquely designed for side-fired operation, usually mounted on existing
side-of-the-road poles or on gantries. For the “overhead” installation it can be mounted on the rails
of the gantries in order to detect the traffic on a specific lane. It maintains accurate detection on any type of road surface, independent of the surroundings and weather conditions - even in tunnels or
on steel bridges, in heavy snow, driving rain, strong winds and scorching sunlight.

The detector operates in either of two microwave bands, employing the FMCW (Frequency Modulated Continuous Wave) principle. It transmits a low-power microwave signal of constantly varying frequency in a fixed fan-shaped beam. The beam "paints" a long elliptical footprint on the road surface. Any non-background targets will reflect the signal back to the RTMS where the targets are detected and their range measured.

The detector’s measurement resolution of 2 metres allows the "slicing" of the footprint ellipse into 32 range-slices. The user can define up to 8 detection zones, each consisting of one or more range slices.

The installed radar detector is calibrated via laptop PC (under MS Windows®). For calibration the
interactive RTMS Setup Program "WinRtms" is executed while watching the flowing traffic.
