Description

This detector employs proper RADAR techniques that permit all vehicles to be detected at

a predetermined range.

Conventional Doppler microwave detectors exhibit a considerable range variation,

(typically 30 - 60 meters dependent on target size). This new unit detects all vehicles,

precisely, from a pre-selected range to near the detector mounting point. Adjustment is

performed using a rotary switch (accessible via a weatherproof plug).

This approach not only provides an accurate detection range but also permits easy

installation since no 'tilt' adjustment is required, only a simple 'pan' adjustment is needed

(an accessory bracket is available for this purpose).

The unit incorporates a microwave patch antenna, which has a well-defined beam pattern.

A low-noise microwave receiver, combined with a microprocessor-based advanced signal

processing module, results in a detector of the highest quality and performance.

The prime application of this microwave detector unit is at signalised traffic installations.

The detector is normally set to detect approaching vehicles travelling above a speed

threshold, however switch settings are available to permit the unit to detect receding or bi-

directional (for shuttle working) traffic.
