3 Introduce

4 Intro. Tsunami Do what How to LEO MEO GEO
Con. Q & A LEO MEO GEO Wikipedia,“Medium Earth orbit”,

5 -> orbital period : 90 to 100 minutes
Intro. Tsunami Do what How to Con. Q & A LEO MEO GEO -> orbital period : 90 to 100 minutes -> use: Resource exploration ,Military Operation, Ocean- Atmosphere observation earthobservatory.nasa.gov/Features/.../page2.php,

6 -> orbital period : 12 hours. -> use: Communication, Navigation,
Intro. Tsunami Do what How to Con. Q & A LEO MEO GEO -> orbital period : 12 hours. -> use: Communication, Navigation, GPS Wikipedia, “Molniya orbit“,

7 Intro. Tsunami Do what How to LEO MEO GEO
Con. Q & A LEO MEO GEO -> orbital period : same as rotation period of earth -> use: meteorological satellite

8 LEO GEO Intro. Tsunami Do what How to LEO MEO GEO Con. Q & A Orbit
Polar Equator Altitude 2000km 36000km Resolution High Low Uses • exploration of resources • Ocean, Atmosphere Observation • Military operation • broadcast • communication • environment satellite NOAA series FY-1series GOES, EUMETSAT, Fengyun, INSAT Advantage • Easy access to data • minimizes risk of missing data • lower in cost • can observe same location Dis- advantage • service fee • shorter life span • same position • more costly to install • Long path length • polar regions cannot be covered. GEO

9 Tsunami

10 Intro. Tsunami Do what How to Tsunami Damage Need
Con. Q & A Tsunami Damage Need

11 6,000 injured 16,000 deaths 2,500 people missing Intro. Tsunami
Do what How to Con. Q & A Tsunami Damage 6,000 injured Need 16,000 deaths 2,500 people missing google,"east japan tsunami",

12 Intro. Tsunami Do what How to Tsunami Damage Need
Con. Q & A Tsunami Damage Need

13 What improved sensor can do

14 Intro. Tsunami Do what How to Now Future
Con. Q & A Now Future East japan tsunami KOSC, KORDI

15 SAR-GEO Intro. Tsunami Do what How to Now Future Con. Q & A
-> exact scale of tsunami -> time of arrival -> exact and real time observation information -> reduce damage -> lessen citizen’s uneasiness -> storm surge, large scale disaster -> permit weather cast more precise

16 spatial temporal resolution
How to improve spatial temporal resolution

17 Intro. Tsunami Do what How to Con. Q & A SAR Resol. Algorithm SAR GEO

18 SAR Effect of broadening antenna But SAR need moving Intro. Tsunami
Do what How to Con. Q & A SAR Resol. SAR Algorithm Effect of broadening antenna But SAR need moving

19 Intro. Tsunami Do what How to Con. Q & A SAR Resol. Algorithm rotating

20 Improved Resolution Temporal resolution 15min spatial resolution 50m
Intro. Tsunami Do what How to Con. Q & A SAR Resol. Improved Resolution Algorithm Temporal resolution 15min spatial resolution 50m 112m per 15minutes We need Improved SAR and GEO rotating orbit and speed

21 algorithm Intro. Tsunami Do what How to SAR Resol. Algorithm
Con. Q & A SAR Resol. algorithm Algorithm Doppler effect Rias coast Light angle

22 Conclusion
