Surabaya C-Band Dual-Polarization Weather Radar

Empowering Nation’s Weather Resilience through Precision Technology

As a leading System Integrator for Meteorological Solutions in Indonesia, SIBAKOM continuously delivers high-precision meteorological, maritime, and infrastructural technology across the archipelago. In a monumental step toward strengthening Indonesia’s climate resilience, SIBAKOM has successfully completed the deployment and integration of the state-of-the-art Surabaya C-Band Dual-Polarization Weather Radar System.

Working in close collaboration with the Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG), this project stands as a testament to SIBAKOM’s technical excellence and unwavering commitment to safeguarding communities through advanced environmental engineering.

Project Overview & Strategic Impact

SIBAKOM was officially contracted to build, install, and integrate a cutting-edge C-Band dual-polarization weather radar system in Surabaya, East Java. This high-tech installation serves as a critical node in Indonesia's meteorological network, significantly expanding BMKG's radar coverage over one of the most densely populated regions in the country.

By successfully executing this project, SIBAKOM has empowered local authorities and the public with dramatically enhanced early warning capabilities, allowing for unprecedented accuracy in predicting severe weather anomalies, intense rainfall, and monsoonal flooding risks.

Understanding the Technology: Why C-Band Dual-Polarization Matters

The Surabaya radar hub utilizes the world-class Baron GEN3-350CM Magnetron Radar System, paired with a robust WRP-43C Pedestal and a high-performance 4.3-meter Parabolic Reflector Antenna. To protect this delicate technology from extreme weather environments, the entire system is housed inside a specialized 5.5-meter pseudo-randomized panel radome.

Unlike conventional radars that only transmit horizontal pulses, "Dual-Polarization" technology sends out both horizontal and vertical radar pulses. This allows the system to gather a highly detailed, two-dimensional picture of atmospheric particles. The radar can instantly differentiate between light rain, heavy downpours, hail, and even non-meteorological debris, providing meteorologists with real-time, highly accurate data.

Vital Benefits of this Technology for Indonesia

As a vast tropical archipelagic nation, Indonesia faces unique and complex climate challenges. The deployment of the Surabaya C-Band Dual-Polarization Weather Radar brings transformative advantages to the region:

• Mitigating Monsoonal Flooding: East Java is highly susceptible to sudden and severe monsoonal flooding. This radar provides localized, high-resolution precipitation data, giving disaster management agencies crucial hours to evacuate citizens and protect assets before floods occur.
• Securing Densely Populated Hubs: Surabaya and its surrounding areas are vital economic engines with millions of residents. Enhanced radar tracking ensures that businesses, infrastructure, and local governments can operate safely with minimize disruptions from unexpected weather events.
• Supporting Aviation and Maritime Safety: Located near major flight paths and busy shipping lanes, this radar system delivers precise atmospheric profiling that helps pilots and maritime captains navigate around severe storms, ensuring the safety of public transportation and regional logistics.

SIBAKOM’s Masterful Execution & Scope of Work

The success of the Surabaya C-Band Radar setup highlights SIBAKOM’s capability to manage highly complex, multi-disciplinary engineering projects from inception to completion. Our comprehensive scope of work included:

• Engineering & Infrastructure: Conducting meticulous site surveys and executing advanced structural engineering to design and secure the radar tower base.
• Precision Installation: Safely hoisting and assembling heavy-duty aerospace components, including the 4.3m antenna panels, feedhorn assembly, pedestal positioner, and the protective 5.5m radome sphere under strict environmental controls.
• Advanced Systems Integration: Powering the facility through tailored industrial UPS units and complex electrical distribution systems, alongside installing specialized aircraft warning obstruction lights and comprehensive lightning protection networks.
• Calibration & Composite Networking: Expertly configuring high-speed signal processors, calibrating dual-polarization parameters for pinpoint accuracy, and seamlessly integrating the radar feed into BMKG’s national radar composite network.

The flawless completion of the Surabaya C-Band Weather Radar is not just a milestone—it is a reflection of SIBAKOM’s long-term vision. We do not just install technology; we build sustainable solutions that protect human lives and bolster national infrastructure.

Moving forward, SIBAKOM is dedicated to remaining at the forefront of environmental technology in Indonesia. We will continue to support BMKG, corporate partners, and local communities by maintaining, innovating, and expanding advanced meteorological networks across the country, ensuring a safer and more climate-resilient future for all.
