  Accurate predictions of electro-optical imager performance are important for
defence decision-making. The predictions serve as a guide for system
development and are used in war game, simulations that directly influence
engagement tactics. In the present study, mathematical models have been
developed which involves detection of different military targets using their
opto-electronics properties in different environmental conditions. The method
first calculates the signal-to-noise ratio received by the observing sensors
reflected from the target by quantifying the light energy in terms of photons,
which is used for evaluating the detection probability.
