Abstract—

The method of digital correction of output signals of multirow infrared (IR) photodetectors (PDs) for detecting small objects is proposed. The method makes it possible to correct the shape of impulse response distorted by high-frequency filtering inside the PD and increase the signal/noise ratio. The presented method is compared with the matched filtering method. The effectiveness of the proposed method for reducing the number of defective “abnormally noisy” PD channels is shown. The source data for calculations are the images obtained as a result of PD tests in a small object detection mode.
