The new approach to the analysis and optimization of remote sensing systems is describe. According to the proposed
concept RS systems should be optimized using energetic - information criterion, which does mean that the maximal
amount of information should be obtained upon fixed value of energy of input signal. The new multi - step principle of
optimization is proposed. The examples of application of this principle are given.
Also the principle of implicit dimensionality lowering for optimization systems with fading and generating signals is
proposed. The principle was used to optimize aerospace remote sensing systems, with varying distance as for as
investigated Earth's surface. Questions related with optimization of systems of active remote sensing taking into
account of energetic losses of sensing signal in the investigated medium are considered. Physical model of such
systems, envisaging energetic losses is considered.
Theorems, optimizing grade regimes of system's output signal when correction of fading is carried out and is not
carried out are proved.
