Defender - Model S Series -S-Band Radar

Big weather needs a big radar

Monsoons. Hurricanes. Cyclones. Blizzards. To make the best long-range predictions of the biggest weather makers, you need to have the biggest radar with the lowest attenuation. Both the Magnetron-powered and Klystron-powered Defender S series are designed and engineered with an output of 850kW to 1000kW - more radiated power than any other commercially available S-Band weather radar!

Coupled with our super-sensitive IQ2 digital receiver and signal processor for precise data processing, these towering S-Band systems are the best choice for a clean and true picture of multiple, long-range, intense weather phenomena.

Additionally, our turnkey design, manufacturing, and installation processes allow us to configure your S-Band radars to meet your specifications. Among the many options are single or dual-polarity transmitters and a variety of full-featured control and display systems. You can even choose the type of installation and radome that best fits your environmental needs.

Introducing EEC’s Defender SK1000H High-Frequency S-Band Radar System

In 2016, EEC became the world’s first weather radar solutions provider to manufacture and deliver a high-frequency S-Band weather radar system. The Defender SK1000H is powered by a 1-megawatt Klystron transmitter and comes standard with dual-polarization capabilities. By operating in the higher end of the S-Band frequency spectrum, 3.5-3.6 GHz, the Defender SK1000H allows users to capitalize on all the advantages of an S-Band weather radar at a much lower price-point. Here’s how it works...

Achieving a beam width less than 1 degree is the "gold standard" by which any weather radar system is measured. Such a beam width speaks to the quality of the antenna and the overall accuracy of the system. A typical S-Band radar system operates in the 2.7 – 3.0 GHz frequency range using an 850kW Klystron transmitter. In order to attain a beam width less than 1 degree, you need a 28-ft (8.53m) antenna. Such a large antenna requires an even larger radome; 40-42-ft (12.2 – 12.8m). All of these large components come with large costs. Additionally, civil works must account for these massive, heavy parts.

The Defender SK1000H operates in the 3.5 – 3.6 GHz range of the S-Band frequency. This means that in order to attain a beam width that is less than 1 degree, you only require a 20-ft (6.09m) antenna. Since the antenna is smaller, so is the radome; 30-ft (9.14m). This, combined with reduced civil works and life-cycle maintenance costs, result in a savings of at least $500,000 as compared to standard frequency S-Band systems! The Defender SK1000H also provides for 250kW more power than a standard S-Band system. EEC’s high-frequency S-Band radar does all this while maintaining the same performance statistics as a standard frequency S-Band system; no impact to sensitivity or detection range. The Defender SK1000H is the perfect combination of S-Band radar performance at an economical price.

Dual-Polarization – The Future Is Here Today

Over 15 years ago, EEC pioneered dual-polarity radar. Today, both of our S-Band models are available with either EEC`s industry-standard single-polarization or with our new, highly advanced dual-polarization system, incorporating features that are years ahead of anything else on the market.

Working with world-renowned experts and the University of Oklahoma, we have developed better algorithms and end-to-end dual-polarization measurements. This not only results in more accurate estimates of rainfall, but also provides better discrimination between different types of precipitation and non-meteorological signals, such as birds, insects, dust storms, or even an approaching tornado`s debris field.

We have also developed proprietary technology to significantly improve clutter suppression performance in our popular and dependable Magnetron systems. The final result is obvious – EEC dual-polarity systems provide the highest resolution data available in the industry.
