Paper Abstract

Prediction of the dynamic performance of the Infrared Background Signature Survey (IBSS) is considered in terms of the expected system response, system noise, photon noise, and signal-to-noise-ratio (SNR). The prediction is based on a preliminary radiometric analysis that facilitates the calibration test program. The IBSS sensor exhibited a design noise-equivalent sterance of 9.72 x 10 exp -9 W/sq cm/sr at 6.86 microns for a 6.13 x 10 exp -6 sr detector, a dynamic range of 1 x 10 exp 6 with three gain ranges, and an SNR between 1 and 2400. Theoretical predictions are found to be in an excellent agreement with measurements.
