N2 - The Georadar (GPR) as a non-destructive technique has been used extensively for geological research. The study was conducted in order to identify coastal sediment characteristics of northern Obi coastal area by performing GPR radar facies analysis. The model of GPR used was Sirveyor 20 with MLF antenna frequency 40 Mhz, penetration depth was 10 meter, and Radan 5 as processing software which include time zero correction, spatial filtering, deconvolution, migration, adjustment amplitude and signal gain. Data interpretation describes georadar image/radargram based on radar facies methodology. The result showed three differences of radar facies unit. The radar facies unit can be divided into 2 facies units in which there are 2 other sub-units, namely unit 1A, 1B, 2A and 2B. Radar facies characterized by medium-high amplitude, continuous parallel-subparallel, medium-weak reflector. At the top part down to 3.75 m is Unit 1A that intersects with 1B. Below 3.75 - 7.75 m depth interval is Unit 2A, and unit 2B is from 7.75-10 meter depth interval. Unit 1 is interpreted as Quartenary alluvium (Qa) and unit B is Woi Formation (Tmpw). Radar facies characteristic indicated the differences of the geological unit.
