Abstract

New variations of minimum noise and correlation energy (MINACE) filters are considered for detection and recognition of objects and rejection of clutter in synthetic aperture radar (SAR) data. We present initial very attractive results that aid different modules in an SAR automatic target recognition (ATR) processor. For four class test set data, we show detection performance of P_D>99.8% with P_FA≅0.026/km²; for classification we show P_C>96.6% with P_FA≅0.026/km². Selected tests with noise and obscurations present and of several objects in large real SAR background are also included. All results used full shift-invariance tests. © 1997 Society of Photo-Optical Instrumentation Engineers.
