Field Operations
Projects Across Scope & Terrains
From high-altitude mountain deployments to naval vessel installations - real field operations across India's most demanding environments.
Three Decades of Precision. Trusted by India's Defense & Space Establishment.
Shanthi Engineering Works (SEW) is a Chennai-based engineering enterprise with over three decades of specialized experience in RADAR systems - from erection and assembly to full commissioning and long-term maintenance.
Founded by S. Rangasamy, SEW has built an unmatched reputation across India's most demanding sectors: national defense, space research, air traffic management, and meteorological surveillance. Our projects span remote mountain terrains, coastal installations, naval vessels, and urban high-rise environments.
As a trusted partner to institutions like ISRO, the Indian Navy, BEL, IMD, NAL, and the Indian Coast Guard, SEW brings government-grade rigor, field engineering excellence, and a commitment to mission-critical precision on every project.
We specialize not just in technical execution, but in the logistical complexity of deploying, relocating, and sustaining RADAR infrastructure across India's diverse and often challenging landscapes.
End-to-end RADAR engineering solutions - from steel erection to system handover - delivered across India's most demanding environments.
Full structural erection of RADAR antenna towers, masts, and lattice steel frameworks. We handle foundation-to-apex assembly with precision alignment for optimal signal performance across all system types.
Expert installation, alignment, and maintenance of protective radomes for all weather and defense RADAR systems. We ensure structural integrity and RF transparency throughout the radome lifecycle.
Comprehensive end-to-end system commissioning including alignment verification, performance testing, calibration, and formal handover documentation. We ensure your RADAR system is operationally certified.
Safe, systematic dismantling of RADAR installations for relocation or decommissioning. We preserve equipment integrity through structured disassembly, transport coordination, and reinstallation at new sites.
Installation and commissioning of Air Traffic Control RADAR systems at airports and defense airfields. We deliver precision-grade ASR and ARSR systems that meet the rigorous standards of DGCA and Indian Air Force.
Specialized installation of Doppler weather RADAR (DWSR), C-band, S-band, and X-band systems for IMD and defense applications. We handle structural, RF, and systems integration for complete meteorological and surveillance capability.
Three decades of government-grade delivery have earned SEW the confidence of India's most demanding defense, space, and scientific organizations.
Representative deployments showcasing SEW's capability across India's most diverse and demanding environments.
Radome and antenna installation atop government administrative building in Chennai - structural assessment, rooftop reinforcement, and commissioning in a dense urban environment.
RADAR tower erected at 3,000m+ altitude for defense surveillance. Extreme weather logistics, helicopter-assisted material transport, and cold-environment commissioning protocols.
RADAR antenna mounted on active lighthouse structure for Indian Coast Guard coastal monitoring. Saltwater environment hardening, structural compatibility analysis, and marine-grade commissioning.
Shipborne RADAR antenna installation aboard Indian Navy vessel. Crane-assisted assembly, vibration-isolated mast mounting, and at-berth systems commissioning with naval engineering teams.
Lattice steel tower erection on open terrain for long-range defense surveillance RADAR. Civil foundation, steel assembly, antenna mounting, and full systems integration with ground equipment shelter.
Large-aperture parabolic antenna installation for ISRO/IMD class applications. High-precision azimuth/elevation alignment, encoder calibration, and RF performance verification against design specifications.
From high-altitude mountain deployments to naval vessel installations - real field operations across India's most demanding environments.
Four core pillars that have made Shanthi Engineering Works the first choice for India's most critical RADAR infrastructure projects.
Three decades of continuous operation across India's defense and space sectors. Our institutional knowledge spans every generation of RADAR technology from legacy analog systems to modern digital phased-array platforms.
Long-standing relationships with the Indian Navy, Coast Guard, BEL, ISRO, IMD, and NAL speak to our reliability. Our track record on classified and strategic projects reflects the highest level of institutional trust.
From Himalayan high-altitude outposts to coastal naval stations and urban installations, SEW has executed projects in every terrain type across India. Our teams are trained for adverse environments and remote locations.
We own the full project lifecycle - from structural erection, RF alignment, and systems integration to formal commissioning and documented handover. Single-point accountability means zero gaps in your project execution.
With over three decades at the helm of Shanthi Engineering Works, S. Rangasamy has built the company from a specialized engineering firm into one of India's most trusted names in RADAR systems deployment. His personal involvement in every major project reflects a philosophy rooted in accountability, technical precision, and mission-first delivery.
Mr. Rangasamy's expertise spans the full spectrum of RADAR engineering - from structural erection and mechanical alignment to electronic commissioning and systems integration. He has personally overseen projects for the Indian Navy, ISRO, IMD, and BEL, earning recognition from client organizations for his hands-on approach and deep domain knowledge.
His leadership philosophy is simple: government-grade quality is not a specification - it is a way of working. Every project executed by SEW reflects this commitment, whether it is a remote mountain installation or a shipborne system deployed in active naval service.
Under his direction, SEW has maintained an unblemished record of on-time, on-specification delivery across India's most demanding defense and scientific programs - a testament to his engineering integrity and leadership depth.
