INTRODUCTION

PRODUCT & TECHNOLOGY

350

The 350 is specifically designed for O.E.M integration
into photo enforcement systems to measure the
position, speed and range of passing vehicles.
Operating in the K-band at 24GHz, the radar offers
market leading performance for demanding
applications such as red light (&speed) and yellow box
violations at signalised intersections.

Positioned in front of (or optionally behind) an
intersection stop line, the 350 will track up to
thirty two targets simultaneously and allows
the setting of two precise trigger
points for data output to the
host system when a
violation occurs.

KEY FEATURES

• Radar reports speed, range and positional data to each event

• Tracks up to 32 simultaneous targets

• Speed measurement from 10kph - 250kph

• Target range 4m - 85m

• 40º field of view

• Suitable for advancing or receding traffic flow

• Dual user selectable virtual trigger points

• High speed RS422 serial communications

• Optional Ethernet interface

• Continuous radar self-check features

• Self calibrating bandwidth control

INSTALLATION

RADAR INSTALLATION - RED LIGHT ENFORCEMENT (RECEDING FLOW)

The nature of the design of the radar lends itself to
versatility in its mounting on the roadway. There are
however, factors to be considered when siting the
radar to ensure optimum performance is achieved.

The radar should be installed at an angle of
approximately 20º from the pavement line and sited
toward the centre of the junction area. The area to
be enforced should be within the ‘D1’ range of the
radar (85 metres max). Mounting height should
be approximately 3 metres from ground level.
Offset (setback) should be approximately 2 metres.
Declination angle of the radar head should be
approximately 10º.

Care should be taken to ensure that the area of
interest is covered by the 40º field of view, this can
be affected by mounting height, correct mounting
angle to the road, correct declination
angle and the radar offset.

RADAR INSTALLATION - RED LIGHT ENFORCEMENT (RECEDING FLOW)

This diagram shows the potential beam coverage of the
350 Radar being used to monitor an intersection for red
light enforcement. The ‘D4’ distance is an important
consideration when adjusting mounting parameters of
the radar.

Adjusting mounting height, offset and mounting angle
will all have the effect of increasing or decreasing the
‘D4’ value. The value is defined as the initial point of
radar coverage on the surface of the roadway. See
diagram below.

RADAR MOUNTING

As highlighted on the previous page(s). There is a certain amount of flexibility in the position of where the
RADAR is mounted. The offset, height, distance from stop line, even orientation in relation to the stop line can
be altered, however when selecting a mounting position, all parameters should be reviewed to ensure that
sufficient RADAR beam coverage of the area of interest, can be achieved at the chosen mounting location.

Selecting a Suitable Site

When choosing to deploy the radar at a location, the following is a non-exhaustive list of considerations which
should be taken into account.

• Does the proposed mounting position give sufficient beam coverage to ‘view’ the enforceable area ?

• Are there any large reflecting surfaces directly in front or behind the RADAR mounting position ?

Radar Speed Accuracy

Simulated target up to 262km/hr ±…….Km/hr
Real target typical accuracy ±…….Km/hr
Radar speed resolution readout 0.1 Km/hr

Radar Range Accuracy

Simulated range up to 70m ±………m
Real target range accuracy ±2m for a range up to 70m
Range readout resolution 0.1m

Radar Angular Accuracy

Simulated angle ±…….º
Real target angular accuracy ±…….º
Angular readout resolution 0.1 º

Radar Angle and Range Modes

The radar has two modes when reporting range and angle. This can be set to a distance based range and

angular approach of the target vehicle, or alternatively, the position of the vehicle can be expressed as an
‘X, Y’ co-ordinate (polar or cartesian).
