BRIEF OVERALL PROJECT SUMMARY:

(1) Detection of ocean oil pollution by Airborne Imaging Radar:
CRL developed an 9.5 GHz Side-Looking Airborne Radar(SLAR) system for the surveillance of detecting oil pollution over the ocean in 1986. SLAR has a very high sensitivity in oil slicks over the ocean. CRL has also been developing the 9.5 Ghz airborne high resolution Synyhetic Aperture Radar(SAR) since 1993.
(2) Development of HF Doppler radar system for measurement of ocean current:
CRL developed a high Frequency (25 Mhz) Doppler radar system, and in the actual observation, dual ocean radars are located at the seashore for monitoring ocean current vectors.

PROJECT OBJECTIVES:

(1) The purpose of this project is to develop the systems for the surveillance of detecting oil pollution over the ocean.
(2) The development of this HF Doppler radar system is to continue measurement of ocean current distributions and sea status over a wide range.

EXPECTED/ACTUAL RESULTS:

These radar technologies will be useful in monitoring marine oil pollution to observe currents and so on.

TARGET GROUPS:

PARTNERS/ACTORS IN THE PROJECT:

Ministry of Posts and Telecommunications, Japan Meteorological Agency, and Maritime Safety Agency of Japan.

USE OF INFORMATION/TELEMATIC TECHNOLOGIES:

Radar technologies (Airborne real aperture Sidelooking Radar, Airborne Synth etic Aperture Radar, Ground-based HF Doppler Radar)

BENEFITS TO THE INFORMATION SOCIETY:

EXPECTED COST:

(1) Airborne real aperture SLAR: about 200 Million Yen
(2) Airborne synthetic aperture radar: about 500 Million Yen
(3) HF Doppler radar: about 200 Million Yen
