High resolution imaging is an important aspect of imaging in missile applications especially for automated target
recognition and tracking. However it is not without its negative aspects. For similar detector size, increase in the
resolution is only possible with decrease in pixel pitch which results a smaller detection area which translates to longer
detection ranges. Binning is a relatively mature feature for silicon detectors used for obtaining better signal to noise ratio.
In this study; a similar concept is proposed for MWIR detectors with emphasis on security related properties such as
detection range and performance of an autonomous/semi-autonomous electro-optical system. The analysis and
simulations has been performed for a fixed sample with predefined optical and electrical properties for noise and signal
models for the clarity of the subject.
To define the ratio of the signal of the desired pixel and the noise of adjacent pixels, noise and signal sources are
theoretically identified. While defining these values, atmospheric attenuation, losses at transmitting surfaces and wave
characteristics of light are considered. For presentation purposes, a standard NATO target is chosen as source object. The
model has been developed for a simple optical design which is intentionally left defective to better address effects of
aberrations to signal to noise ratio of adjacent pixels especially caused by diffraction.
