Ground-based infrared imaging tracking system (GIITS) is of great importance for aerial target warning and guard. The operating range is one of the key performance specifications
on the other
which should be calculated
calculate the radiation power received on the detector in order to analysis whether the output signal meets the detection requirements or not
analyzed and studied during the whole GIITS design process. The operating range is mostly influenced by a few factors
without considering the effect of the background radiation. By improving of the traditional method
including atmospheric attenuation
a new operating range calculation model of the GIITS was established based on two requirements. One is that the image size of observed target should meet the requirement of the processor signal extraction. The number of the pixel occupied by target image should be more than 9. The other is that the signal noise ratio (SNR) of the GIITS should not be less than 5 to meet the requirements of the target detection probability and spatial frequency. The SNR calculation equation in form of energy is deduced and the radiation characteristic of the observed target and background are analyzed. When evaluate the operating range of the GIITS using the new method
the performance of GIITS and feature of target and background. This paper firstly makes analysis and summarization on the definite localizations of the traditional operating range equation of the GIITS. The localizations are mainly in two aspects. On one hand
we should successively calculate two operating range values according to two requirements mentioned above and choose the minimum value as the analytic result. In the end
the dispersion of the image and the effect of image dispersion are not considered in the traditional method
an evaluation of operating range for fighter aircraft is accomplished as an example. The influence factors in every aspect on operating range were explored by the calculated result. The new operating range calculation model provides the theoretical basis for the design and applications as well as the comprehensive evaluation of a GIITS. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
