Abstract
The article presents a method for the detection of soil oil contamination in coastal areas using onboard hyperspectrometers - the signals informational balance method of dispersive and non-dispersive probing, used respectively for basic and validation measurements. Remote sensing is a potentially promising method for detecting various types of coastal environment pollution, including pollution by petroleum hydrocarbons. The general principle of remote presentation is the obligatory carrying out of remotely validation obtained results. The principles and methods of carrying out validation measurements are diverse and can be classified according to the following features: 1) synchronization of basic and validation measurements; 2) autonomy validation measurements; 3) select the height of the validation measurements. The proposed method operational algorithm is described. A variant of joint and synchronous basic and validation measurements using a hyperspectrometer installed on a low-altitude aircraft is considered. The mathematical model of the used method is given. Based on the information balance condition, an expression is obtained for determining the signal-to-noise ratio in the system in order to further calculate the correlation between the narrow-band oil index and the broadband signature-based sign of the heavy metals anomalous concentration.
