SUMMARY:Techniques for Detection of Relative Oil Thickness using Spaceborn
 e SAR
DESCRIPTION:Poster\n\nGordon Staples (MDA)\n\nThree techniques for the est
 imation of relative oil thickness were compared. The first technique used 
 the Damping Ratio (DR). The second technique used RADARSAT-2 quad polarize
 d data, and third technique entailed the use of Compact Polarimetry (CP) d
 ata which is available from the RADARSAT Constellation Mission (RCM). \nTh
 e DR was given by (σwater / σoil), where σ is the radar backscatter. The C
 loude-Pottier entropy was extracted from a RADARSAT-2 QP image acquired of
 f the coast of Louisiana. There was good agreement with the expected respo
 nse of the polarimetric parameters for ocean-slick discrimination.  Furthe
 r, the response and spatial variability of the parameters agreed favorable
  with an oil thickness estimates derived from application of a Maximum Lik
 elihood Classifier using ASTER and WorldView images. \nA RCM 5M CP image (
 5 m resolution, 30 km x 30 km scene size) was acquired June 26, 2022. Thre
 e CP parameters were selected for slick discrimination analysis: Degree of
  Circular Polarization, Degree of Polarization, and Entropy. Although ther
 e was variable performance for the discriminators, in general the measured
  values agreed with the expected values. \nFuture work will focus on the a
 cquisition of the RCM 30 m and 50 m resolution CP data over the Santa Barb
 ara study site. A key advantage of the 30 m and 50 m resolution modes is t
 he lower noise floor, ~ -34 dB, relative to the 5 m resolution RCM mode.\n
