Recently, the “Chip-to-System Synergy, Advancing Perception” — Cheng-Tech × Infineon Ecosystem Collaboration Ceremony and Distributed Radar System Launch was held in Shenzhen.

At the event, Cheng-Tech presented Infineon with an Ecosystem Partner plaque and officially unveiled its latest R&D achievements in distributed radar systems. Building on their existing collaboration, the two companies will continue to deepen cooperation in automotive millimeter-wave radar chips, radar systems, and advanced perception solutions, jointly advancing intelligent driving perception.

01 / Deep Chip-System Collaboration to Advance Radar Perception

As intelligent driving moves toward centralized computing and AI-powered sensor fusion, vehicles require increasingly advanced environmental perception capabilities. Millimeter-wave radar is no longer simply a standalone sensor for range, velocity, and object detection. It must provide higher-quality, more continuous sensing data that is better suited for fusion and centralized processing, enabling vehicles to better understand and respond to complex environments.

Against this backdrop, advances in radar performance increasingly depend on close co-design between semiconductor capabilities and radar system architecture. Chips determine the underlying quality of radar data acquisition and the signal chain, while radar systems determine how those capabilities are translated into perceivable, integrable, and mass-producible solutions.

The collaboration between Cheng-Tech and Infineon reflects this industry trend. By recognizing Infineon as an ecosystem partner, Cheng-Tech not only acknowledges the achievements of their existing cooperation, but also further reinforces the shared direction of innovation toward centralized computing architectures and AI-powered sensor fusion.

02 / Breaking Performance Limits Through Architectural Innovation: Distributed Radar System Officially Launched

As a key outcome of the event, Cheng-Tech officially launched its distributed radar system.

Designed for centralized computing architectures and AI-powered intelligent driving, the system is not simply about adding more radar units. Instead, it redefines millimeter-wave radar perception at the architectural level.

Fang Yongjun, Deputy General Manager of Product & R&D at Cheng-Tech, introduces the distributed radar system.

Conventional standalone radar is constrained by physical size, antenna channel count, power consumption, and cost, making further performance improvements increasingly difficult.

Through distributed deployment and coherent synchronization, Cheng-Tech’s distributed radar system combines multiple radar nodes into an equivalent “virtual large aperture” at the signal-processing level, achieving a system-level leap in perception performance without simply stacking more channels.

Built on a centralized computing architecture, the system sends high-quality raw radar data to the central computing platform, where coherent synthesis, signal processing, and AI perception algorithms are performed at the domain controller.

This transforms radar data from locally processed sensor outputs into low-level sensing data that can be fully utilized for centralized fusion and computation.

In terms of performance, the distributed radar system delivers significant improvements in resolution and angle estimation accuracy.

The system achieves azimuth resolution at the 0.2° level, elevation resolution at the 0.3° level, approximately 5× higher angle estimation accuracy, and reduces long-range lateral position jitter to around one-tenth of that of conventional solutions.

This enables vehicles to obtain more stable and reliable perception results in scenarios such as distinguishing adjacent vehicles at long range, identifying elevated objects, and accurately locating targets on complex roads.

These achievements also signal a new stage in the evolution of millimeter-wave radar technology. Going forward, radar will no longer serve only as a functional sensor in driver assistance systems. It will increasingly evolve into a data-centric perception system for centralized computing, creating greater value for advanced intelligent driving, full-domain perception, and safety redundancy in complex scenarios.

03 / Bringing Advanced Perception into Real-World Mobility

The value of advanced perception technology must ultimately be proven in real-world driving scenarios.

For OEMs, system-level perception solutions represented by distributed radar can further improve perception stability on highways, urban roads, and under challenging conditions such as rain, fog, and nighttime driving, providing a more reliable data foundation for advanced driver assistance and future automated driving.

For the broader industry ecosystem, the collaboration between Cheng-Tech and Infineon sends a clear signal:

Competition in intelligent driving is shifting from isolated hardware performance toward integrated capabilities across semiconductors, sensor systems, AI algorithms, and mass-production engineering. Underlying semiconductor capabilities are a critical foundation for the evolution of next-generation perception architectures.

As an important technology platform supporting the evolution of intelligent driving perception architectures, Infineon’s RASIC™ CTRX family of millimeter-wave MMICs continues to advance automotive radar RF platforms.

The CTRX8188F, the industry’s first mass-produced single-chip 8-transmit, 8-receive (8T8R) millimeter-wave MMIC, is built on an advanced automotive-grade 28 nm RFCMOS process platform and represents an architectural evolution from dual-chip cascading to single-chip integration.

Its single-chip 8T8R architecture, combined with a single CSI-2 raw data output, reduces system complexity, peripheral component count, and BOM cost, while providing a highly integrated RF platform for high-performance automotive radar.

The CTRX8188F also integrates an on-chip digital phase-locked loop (DPLL), delivering low phase noise, high frequency stability, and strong RF performance. These capabilities further enhance radar detection performance, angular resolution, and sensing stability in complex environments, providing a reliable semiconductor foundation for next-generation intelligent driving radar.

From semiconductor innovation to system-level implementation, Cheng-Tech and Infineon will continue to advance perception technologies from architectural innovation toward large-scale deployment, ultimately translating technical progress into a safer, more reliable mobility experience.

04 / Conclusion

From the mass-production deployment of InsightRadar satellite radar to the forward-looking development of distributed radar systems, the collaboration between Cheng-Tech and Infineon continues to deepen.

Looking ahead, Cheng-Tech will build on its mass-production capabilities and continue to advance millimeter-wave radar through next-generation perception technologies, accelerating its evolution from a functional sensor into a data-centric sensor for the AI-powered intelligent driving era.

Cheng-Tech will continue to provide the intelligent driving industry with radar perception solutions that are verifiable, integrable, and scalable for mass production.
