The two wavelength active monostatic infrared sensor detects the anomalous dispersion that occurs in petroleum products as a result of the carbon-hydrogen stretch bands near 3.4 micrometers. By ratioing the reflected power received at the two wavelengths the quotient is a signature proportional to reflectivity only, being independent of common mode effects such as range and time variable surface roughness caused by waves. Field tests were successfully conducted on both inland and ocean waters.
