The article presents the approach to the design wide-angle optical systems with special illumination and instantaneous
field of view (IFOV) requirements. The unevenness of illumination reduces the dynamic range of the
system, which negatively influence on the system ability to perform their task. The result illumination on the
detector depends among other factors from the IFOV changes. It is also necessary to consider IFOV in the synthesis
of data processing algorithms, as it directly affects to the potential "signal/background" ratio for the case
of statistically homogeneous backgrounds. A numerical-analytical approach that simplifies the design of wideangle
optical systems with special illumination and IFOV requirements is presented. The solution can be used
for optical systems which field of view greater than 180 degrees. Illumination calculation in optical CAD is based
on computationally expensive tracing of large number of rays. The author proposes to use analytical expression
for some characteristics which illumination depends on. The rest characteristic are determined numerically in
calculation with less computationally expensive operands, the calculation performs not every optimization step.
The results of analytical calculation inserts in the merit function of optical CAD optimizer. As a result we reduce
the optimizer load, since using less computationally expensive operands. It allows reducing time and resources
required to develop a system with the desired characteristics. The proposed approach simplifies the creation and
understanding of the requirements for the quality of the optical system, reduces the time and resources required
to develop an optical system, and allows creating more efficient EOS.
The article presents the concept of network-centric conformal electro-optical systems construction with spherical
field of view. It discusses abstract passive distributed electro-optical systems with focal array detectors based on
a group of moving objects distributed in space. The system performs conformal processing of information from
sensor matrix in a single event coordinate-time field. Unequivocally the construction of the systems which satisfy
the different criteria of optimality is very complicated and requires special approaches to their development
and design. The paper briefly touches upon key questions (in the authors' opinion) in the synthesis of such
systems that meet different criteria of optimality. The synthesis of such systems is discussed by authors with the
systematic and synergy approaches.
