class of forests against the Nesterov’s or any other local
scale .
The algorithm is so formed that it does not require an
any prior information, except for the knowledge over what
kind of forest the transducer is: coniferous, mixed with
coniferous species accounting for not less or more than
40 c h or foliage .
Realization of this algorithm requires the radiometer
with wavelength range of 0.3 to 4 cm with terrain resolu
tion from tens to hundreds of meters.
The above-mentioned examples point to both expediency
of attracting the microwave radiometric measurements for
decoding the aerospace photos and possibility of solving
the inverse problem: interpretation of radio-thermal infor
mation for the purpose of construction of special (radio-
thermal) terrain maps.
'or operative solution of the above-mentioned uroblem;
the programs have been worked out for the joint processing
of photo— and radio-thermal images on the information re
presenting complex "Swit-Izot”. The programs have been
worked out for sequential and simultaneous display of
photo- and radio-thermal images on the TV monitor screen
die ir relative turning and scaling for the purpose of
alignment of the images and determination of qualitative
and quantitative characteristics of the objects being in
vestigated (registergrams and hystograms of brightness cha
racteristics in the preset cross-sections and over the
field as a whole, their calibration, statistical charac
teristics of elements of the images, etc.). The examples of
the joint processing of images on the screen of the complex
are shown in Figs 3, 4, 5, 6.
