Abstract
The effect of anomalous (with respect to noise power spectral density) TDI channels on the probability of detection of small objects by FPAs is considered. A series of FPA output images simulating the signals of TDI channels with four main types of noise PSDs is generated, the probability of detection of a small object is calculated, and the efficiency of various combinations of linear filters used in intraframe processing is evaluated. It is found that TDI channels with low-frequency noise most significantly affect the probability of detection of a small object, and the successive application of an adaptive recursive filter and a window filter that is quasi-matched with the signal leads to an increase in the probability by 22% even in the presence of 6% anomalous TDI channels in the FPA.
