Stalker Dual SL Police Radar Using True Doppler Audio for High Performance Radar Stalker Radar

Stalker Dual SL Police Radar uses True Doppler Audio to ensure High Performance Police Radar.

The Longest Range
The Stalker DUAL SL sets the standard in the industry for range and performance. The best performance means monitoring every vehicle at greater distances, which results in superior tracking history and better target identification.

3 Window Fastest Speed Tracking
Stalker's patented Fastest Speed Tracking assists the operator in making proper target identification by displaying both the Strongest and Fastest targets simultaneously on separate display windows.

Four Direction Speed Monitoring

With two antennas, the Stalker DUAL SL's moving mode can track vehicles in four directions:
• In Front of the Patrol Moving the Same Direction
• In Front of the Patrol Approaching in the Opposite Direction
• Behind the Patrol Moving in the Same Direction
• Behind the Patrol Receding in the Opposite Direction

True Doppler Audio
The Stalker DUAL SL compensates for patrol speed variations when generating the Doppler audio. Since the audio tones do not vary with patrol speed, the operator learns to correlate this true Doppler audio with target speed, which eliminates the need to constantly watch the display to determine target speed.

The Most Sophisticated Ka Band Antenna System

The Stalker Dual SL's Ka Band antenna helps the radar achieved incredible performance.

Balanced Mixers
The extremely sophisticated Ka band antennas use two mixer diodes (every other radar available uses just one diode). By averaging the Doppler signal from two diodes, the ending signal is much cleaner (less static or noise). The reduced signal noise increases sensitivity and allows the radar to achieve much longer range.

Patented Digital Antenna Communication

The Stalker DUAL SL achieves longer range by digitizing the Doppler audio signal at the antenna and using a high-speed bi-direction communication link to transmit data between the antenna and the counting unit. Other two-piece radar units (even DSP radar units) send a low level Doppler audio signal from the antenna to the counting unit for processing and speed display. This method is susceptible to noise induced by the auto ignition and 2-way radio transmissions, which result in reduced range and increased potential for false signals.

O-Ring Sealed Waterproof Design
The completely waterproof Ka band antenna features O-ring seals and connectors. The antenna can be exterior mounted with no reliability concerns.
