Effect of signal-to-clutter ratio on template-based ATR

摘要: In this work, we evaluate the robustness of template matching schemes for automatic target recognition (ATR) against effects clutter layover. The results our experiments indicate performance ATR in various image transform domains signal to ratio (SCR). purpose these transforms is enhance features a chip while suppressing representative background or simple noise. were performed synthetic aperture radar imagery using chips public domain MSTAR database. include pointwise nonlinearities such as logarithm and power operations. templates are generated training portion database at nominal SCR. Many different parameterizations considered each where built represent ranges aspect angles uniform angular bins 5, 10, 15, 30, 45 degree increments. ATRs evaluated testing was added lower
