This paper reports on the IR system level modeling for a FPA based on type II superlattice photodiodes. The predicted
performance of the super lattice detectors is based on published values from device models and measured results. A top
level description of the sensor model is given and how it is used to determine system level trades. Results of these
trades provide valuable feedback to developers of type II superlattice devices, arrays and readout circuits. Trades
between IR FPA technologies can be made to aid the IR system developer to make informed decisions relative to risk
and performance early in the program cycle. IR band selection is a complex trade of target signature, background,
detector technologies and optical response. This paper explores these considerations for single and multicolor
BAE SYSTEMS reports on a program to characterize the performance of MEMS corner cube retroreflector arrays under laser illumination. These arrays have significant military and commercial application in the areas of: 1) target identification; 2) target tracking; 3) target location; 4) identification friend-or-foe (IFF); 5) parcel tracking, and; 6) search and rescue assistance. BAE SYSTEMS has theoretically determined the feasibility of these devices to learn if sufficient signal-to-noise performance exists to permit a cooperative laser radar sensor to be considered for device location and interrogation. Results indicate that modest power-apertures are required to achieve SNR performance consistent with high probability of detection and low false alarm rates.
