About Us

Pioneer of Japanese radar systems and VTS systems markets

Japanese Quality and User-Centered Design

TOKYO KEIKI pioneered the manufacture of Japan's first radar system in 1952. Through dedicated and sustained effort since that beginning, we have achieved an unparalleled level of expertise in manufacturing and engineering. Our products are renowned for their superior quality, reflecting our reputation for reliability, long life, and high performance.

Experienced in radar systems and VTS systems_markets

Challenges in the VTS and Coastal Surveillance Markets

We have been providing products and solutions to the VTS (vessel traffic services) and surveillance markets since 1964. Our success is attributable to the invaluable experience and knowhow gained over the years in dealing with our challenging circumstances. They include coping with our immediate geography, with its myriad of large and small islands, and a temperate regional environment of heavy rain and frequent typhoons.

Radar systems and VTS systems based on Defense industry technologies

A Manufacturing Tradition Steeped in the Defense Industry

With a long manufacturing tradition dating back to the company's establishment in1896, we have contributed significantly to Japan's industrial modernization as a major provider of precision products and solutions to industry. Today, our products play an active role in national security, safety, the achievement of higher efficiencies and protection of our environment.

Miracle Images

High difinition Ku band solid state Radar systems

The Possibilities of Ultra High Definition

Ku-Band Solid State Radar (SSR) systems with their greatly enhanced ability to detect very small objects have elevated surveillance to the next level. Compared to conventional X-Band radar systems, Ku-Band radar systems with high gain antenna achieve the higher resolutions required for vessel aspect discrimination.

Ku band solid state Radar systems resolve the interface issue

Resolving the Interference Issue

Ku-Band Solid State Radar (SSR) systems eliminate the problem of interference between offshore X-Band radar systems and ship-borne X-Band radar systems. Radar interference is no longer a concern even under extreme circumstances where there are multiple operating X-Band radar sites and heavy ship traffic.

Ku band solid state Radar systems super performance in bad weather

Superior Performance in Bad Weather

The high detection capability of Tokyo Keiki's Ku-Band SSR system even under severe weather conditions is enabled by our unique signal processing technology that incorporates major enhancements. These enhancements include improved range sidelobe levels based on a proprietary chirp pulse compression method, cost-effective component integration and combination of pulse-Doppler and clutter removal processing.

World's Most Powerful and Reliable X-Band Radar System

Tokyo Keiki's innovative radar systems merge state-of-the-art microwave devices and cutting-edge signal processing technologies. Our high-powered solid state power amplifiers (SSPA) and signal processing knowhow ensure clearer images. And optimization in system design has enabled realization of radar systems of unparalleled detection capabilities.

X band solid state radar systems is cost effective

Cost Effective

Compared to magnetron type radars, our solid state radars boast greatly reduced running costs with great savings in power consumption. In addition, there are fewer parts that may deteriorate over time and you can also eliminate the service work associated with replacing magnetron type radar systems.

X band solid state radar systems comply with IALA_V-128

IALA Recommendation V-128 Compliant

Our SSR system complies with IALA Recommendation V-128 and the demands and requirements of VTS and coastal surveillance. We also place important consideration on and are always receptive to other customer requests which are not addressed in IALA Recommendation V-128.
