Sensor Modelling for the 'Cyclops' Focal Plane Detector Array Based TechnologyDemonstrator

摘要

The Surveillance Research Laboratory of the DSTO has developed a technologydemonstrator utilizing an infrared focal plane detector array to assess the feasibility of using large scale infrared detector arrays for ADF applications. The imaging sensor which has been developed requires no scanning mechanism and uses an array of mercury cadmium telluride detectors sensitive to radiation in the 8 um to 12 um spectral region to produce an image. The sensor was tested in a series of airborne trails and the results obtained from these trials will be used to evaluate the performance of focal plane detector array based systems. A mathematical model of the sensor has been used to evaluate the performance of the sensor. The mathematical model has been developed to meet the requirements imposed by analysis of the performance of this sensor. The model is based on the description of the operation of the elements of the detector array as photon counters. A description of the model used for the analysis of the data obtained using the sensor is presented here.... Infrared detectors, Focal plane arrays, Performance evaluation, Mathematical models.
