4. CHIRP Pulse Compression Technology Explained

The Quantum Q24C uses CHIRP (Compressed High-Intensity Radiated Pulse) technology. Traditional radar systems emit a single-frequency pulse, while CHIRP radars emit a range of frequencies in each pulse. This results in:

• Better target resolution

• Improved signal-to-noise ratio

• Clearer images at both short and long ranges

• Less clutter in tight, high-traffic areas

This makes it especially useful for collision avoidance, weather detection, and navigating through narrow channels.

5. Advantages of Solid-State Radar

Unlike traditional magnetron radar systems, the Quantum Q24C is solid-state, providing several benefits:

5.1. No Warm-Up Time

Start navigating instantly. The radar is ready to go the moment you power it on.

5.2. Lower Power Usage

Consumes less power—perfect for sailboats and smaller powerboats with limited electrical systems.

5.3. Longer Lifespan

Solid-state systems have fewer moving parts, resulting in less maintenance and longer durability.

5.4. Safer Emissions

Because it operates with lower transmission power, the Q24C emits minimal radiation, making it safer for passengers and crew.

6. Installation and Compatibility

6.1. Easy DIY Installation

The lightweight, compact dome can be mounted on most radar masts or radar arches. The Wi-Fi model allows wireless connection, reducing the need for bulky cables.

6.2. Raymarine System Integration

Compatible with:

• Raymarine Axiom series

• Raymarine eS and gS series

• LightHouse II and III operating systems

You can connect it via Wi-Fi or RayNet Ethernet depending on the model you choose.

7. Performance in Real-World Conditions

7.1. Short-Range Precision

Detects targets as close as 18 feet, making it ideal for docking, anchoring, or avoiding floating debris.

7.2. Long-Range Clarity

With a maximum range of 24 nautical miles, it provides clear detection of distant targets including ships, landmasses, and squalls.

7.3. Weather Penetration

Unlike some lower-end solid-state radars, the Q24C can penetrate rain and fog, ensuring visibility during bad weather.
