ABSTRACT: It is well-known that according the Dozier’s method, utilization of
integral of Planks function in fusion of signals of two different channels of airborne
radiometer makes it possible to compute such components of temperature field
within one pixel as temperatures of the object and background. In the paper,
the generalization of Dozier method is suggested. The suggested generalization
of Dozier’s bispectral method named as biparametric method is applicable for
static remote objects. In the suggested biparametric method, the measurements
are carried out at the moments t1 and t2. It is assumed that
the object temperature reaches quantity T(t1) and T(t2) at these
moments. On the bases of operational data of scanning infrared radiometer, the
square area of one pixel can be calculated in dependence of distance between
object and radiometer. This makes it possible to carry out location of static
objects from two basis points using serial single wavelengths measurements of
radiation emitted by the sub pixel object.
