Paras Defence and Space Technologies Limited has signed a tripartite Memorandum of Understanding with Complus Systems Private Limited and JV Micronics to develop advanced Anechoic and Semi-Anechoic Chambers. These specialized facilities are critical for testing radar systems, antennas, and electronic warfare technologies in environments free from electromagnetic interference. The consortium aims to provide end-to-end solutions for India’s growing electromagnetic testing infrastructure needs, supporting the nation’s push for self-reliance in defence electronics.
Strengthening India’s Defence Testing Infrastructure
The tripartite agreement establishes a new specialized business vertical dedicated to high-precision defence testing environments. Paras Defence, acting as the consortium leader, will oversee the overall design, development, and manufacturing of the chambers. The collaboration leverages the complementary strengths of three Indian entities to provide domestic alternatives to international testing standards.
Paras Defence and Space Technologies Limited, headquartered in Navi Mumbai, is a prominent Indian private sector company involved in defence and space engineering. Established in 2009, the firm operates across several critical verticals, including defence optics, electronics, and electromagnetic shielding. By leading this consortium, Paras Defence aims to consolidate India’s position in the niche market of specialized testing infrastructure.
The other partners, Complus Systems Private Limited and JV Micronics, provide the technical and manufacturing backbone for the project. Complus Systems, based in Bengaluru, brings over 30 years of experience in Radio Frequency (RF) and microwave electronics. Meanwhile, JV Micronics, operating from Faridabad, specializes in the production of high-performance RF absorbers and microwave components, ensuring the chambers meet stringent military specifications.
Understanding Anechoic and Semi-Anechoic Chambers
Anechoic chambers are specialized rooms designed to be completely free of echoes or reflections. The term anechoic literally means “non-echoing.” These chambers act as a Faraday Cage, preventing external electromagnetic noise from entering and internal signals from escaping. They are essential for ensuring that electronic devices comply with global Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) standards.
The Science of “Echo-Free” Testing
The interior surfaces of an Anechoic Chamber are entirely covered with Radiation-Absorbent Material (RAM), often shaped like foam pyramids. These materials absorb electromagnetic waves, preventing them from reflecting off the walls, ceiling, or floor. This setup creates a “free-space” environment, which is necessary for testing the precision of antennas and sensitive military sensors.
A Semi-Anechoic Chamber differs in its construction by featuring a conductive, reflective metal floor while the walls and ceiling remain covered with RAM. This design simulates a “half-space” environment, replicating conditions where a device sits on the ground. These facilities are primarily used for testing larger equipment, such as military vehicles and industrial machinery, to observe how they perform in real-world ground-plane conditions.
| Feature | Anechoic Chamber | Semi-Anechoic Chamber |
|---|---|---|
| Absorber Coverage | All six surfaces (including floor) | Five surfaces (walls and ceiling) |
| Floor Type | Covered in RAM | Reflective metal floor |
| Simulated Environment | Free-space (no reflections) | Ground-plane (half-space) |
| Primary Use | Antennas and small electronics | Large vehicles and heavy equipment |
Roles and Responsibilities within the Consortium
The success of the tripartite collaboration depends on the specific expertise each partner contributes to the development lifecycle of these testing facilities. As the consortium leader, Paras Defence is responsible for the overall strategic direction, business development, and the core manufacturing and installation of the chambers. This includes the integration of specialized filters and engineered points of entry that maintain the chamber’s electromagnetic integrity.
Complus Systems plays a vital role by providing technical consultancy and procuring advanced instrumentation. Their expertise in project execution ensures that the testing systems are calibrated to meet international benchmarks. On the manufacturing side, JV Micronics focuses on the production and integration of the specialized RF absorbers. These components are the building blocks of any anechoic environment, as they are responsible for the absorption of unwanted signals.
Strategic Importance for Electronic Warfare and Radars
The development of advanced anechoic chambers is a critical prerequisite for the evolution of India’s Electronic Warfare (EW) and radar capabilities. In modern combat, the ability to operate in a contested electromagnetic spectrum is as important as physical firepower. Electronic warfare systems, which include jamming devices and signal interceptors, must be tested in controlled environments to ensure they do not interfere with friendly communications or navigation systems.
Similarly, radar systems and antennas require precise calibration to detect stealthy targets and operate across various frequency bands. Without locally available advanced testing infrastructure, Indian defence manufacturers often rely on foreign facilities for certification. This not only increases the cost and timeline of project development but also poses security risks regarding sensitive military data. By establishing these facilities domestically, India can accelerate the induction of indigenous platforms like the Shakti EW suite for the Navy and various airborne radar warning receivers.
Boosting “Atmanirbhar Bharat” in Defence Electronics
The tripartite MoU aligns with the Government of India’s Atmanirbhar Bharat (Self-Reliant India) initiative and the “Make in India” programme. It addresses a significant gap in the domestic aerospace and defence supply chain. Historically, India has relied on specialized government laboratories like SAMEER (Society for Applied Microwave Electronics Engineering & Research) and various DRDO labs for such testing. However, as the private sector’s role in defence production grows, the demand for accessible and high-quality testing infrastructure has surged.
By creating an end-to-end domestic solution for electromagnetic testing, the consortium reduces the dependency on global technology providers. This move is expected to benefit not only large-scale defence projects but also the burgeoning ecosystem of small and medium enterprises involved in electronics and telecommunications. Moreover, the ability to offer these services to international markets could position India as a global hub for specialized defence testing and certification.
