76 GHz Millimeter-Wave Radar Blind Spot Warning

Traditional camera-based monitoring systems can experience reduced performance in darkness, rain, fog, and strong backlight environments, while conventional 24GHz radar solutions often have limitations in detection distance and target resolution. BOSHI 76 GHz Millimeter-Wave Radar Blind Spot Warning adopts advanced FMCW radar technology to achieve longer-range detection, higher measurement accuracy, and stable operation under complex weather and lighting conditions.

With a 2Tx4Rx multi-channel antenna structure, up to 70m detection capability, ±55° horizontal field of view, and integrated BSD (Blind Spot Detection), LCA (Lane Change Assist), and RCW (Rear Collision Warning) functions, this radar provides a complete active safety solution for motorcycle manufacturers, fleet operators, and aftermarket suppliers.

Advanced 76GHz Radar Technology for Two-Wheeler Safety

1. Why Choose 76GHz Millimeter-Wave Radar Instead of Camera and 24GHz Radar?

Two-wheelers frequently encounter blind spot risks because of their compact body design and limited rear visibility. During urban commuting, highway riding, and delivery operations, vehicles approaching from the side or rear may not be detected in time through traditional mirrors.

Compared with camera-based systems, BOSHI 76GHz Millimeter-Wave Radar is not affected by darkness, rain, fog, or strong sunlight because it detects objects through electromagnetic waves instead of visible images. Compared with traditional 24GHz radar, the 76GHz frequency provides higher resolution, more accurate target positioning, and stronger ability to identify fast-approaching vehicles.

Core Performance and Functional Advantages

1. High-Precision FMCW 76GHz Radar Architecture

BOSHI 76 GHz Millimeter-Wave Radar adopts FMCW (Frequency-Modulated Continuous Wave) technology with a 2Tx4Rx antenna configuration. The multi-channel radar structure improves target detection capability and enables accurate measurement of distance, speed, and direction.

The radar can detect approaching vehicles up to 70 meters away with a distance resolution of 0.42m and ranging accuracy of 0.21m. Its ±55° horizontal and ±45° vertical detection range effectively covers the side and rear blind zones of motorcycles, allowing riders to receive earlier warnings before dangerous situations occur.

The system supports a speed measurement range of ±200km/h, speed accuracy of 0.04m/s, and angular accuracy below 1°, enabling accurate identification of whether a rear vehicle is approaching quickly, maintaining speed, or moving away.

2. Integrated BSD, LCA and RCW Active Safety Functions

BOSHI 76GHz radar combines three important motorcycle safety functions into one compact radar system.

The BSD Blind Spot Detection function continuously monitors vehicles entering the motorcycle blind area. When another vehicle approaches from the side rear position, the warning system reminds the rider before changing lanes or overtaking.

The LCA Lane Change Assist function analyzes the distance and speed of vehicles approaching from behind. When the system detects a dangerous closing speed, it provides enhanced warning signals to prevent unsafe lane changes.

The RCW Rear Collision Warning function monitors vehicles directly behind the motorcycle. When a fast-approaching vehicle creates a potential collision risk, the system provides early warnings to help riders take protective actions.

The radar automatically activates when vehicle speed reaches 10km/h, ensuring continuous safety monitoring during daily riding.

Technical Specifications

Reliability and Integration Capability

1. IP67 Protection and Extreme Environment Operation

Motorcycles are frequently exposed to outdoor environments including rain, dust, temperature changes, and direct sunlight. BOSHI 76GHz Millimeter-Wave Radar adopts an IP67 waterproof and dustproof design, allowing installation at the rear of motorcycles without additional protective housing.

The radar has been tested under extreme temperature conditions from -40℃ cold start to 80℃ continuous operation. Detection accuracy and warning logic remain stable without signal interruption, making it suitable for motorcycles used in different climate regions worldwide.

2. Flexible Communication Interfaces for Vehicle Integration

To meet different vehicle manufacturers’ requirements, BOSHI radar supports TTL and CAN communication interfaces. The system can connect with motorcycle wiring harnesses, warning indicators, TBOX systems, and intelligent vehicle controllers.

This flexible integration design allows the radar to be installed as an original equipment safety module or used for aftermarket motorcycle upgrades.

Real Application Cases

1. Urban Electric Motorcycle Delivery Fleet Safety Upgrade

A city delivery company operating hundreds of electric motorcycles needed to reduce safety risks caused by frequent lane changes and dense urban traffic. After installing BOSHI 76GHz Millimeter-Wave Radar systems, riders received earlier warnings when vehicles approached from side and rear blind areas.

The radar helped delivery teams improve rider awareness during rush hours, night operations, and rainy conditions, while supporting safer fleet management through active warning technology.

2. Motorcycle OEM Premium Model Safety Upgrade

A motorcycle manufacturer planned to add advanced safety functions to improve the competitiveness of its premium models. BOSHI 76GHz Millimeter-Wave Radar was selected because of its long detection range, compact design, IP67 protection, and compatibility with motorcycle electronic systems.
