چکیده
In this work we present a new algorithm that enable to perform automatic target recognition (ATR) in high-resolution synthetic aperture radar (SAR) data. According to the microwave backscattering theory and the three-dimension model of target, we calculate radar cross section (RCS) and correspondingly obtain the high resolution inverse synthetic aperture radar (ISAR) image of target. In order to discard most of the false alarms, a discrimination algorithm integrated two discriminators is proposed. Then, the target is recognized rapidly and accurately based on the simulated signatures. Finally, evaluation of ATR performance using high-resolution SAR image of the Chinese airborne SAR system is conducted. Keyword:SAR, ISAR, high resolution, radar cross section, target recognition

Double Weight-Based SAR and Infrared Sensor Fusion for Automatic Ground Target Recognition with Deep Learning
This paper presents a novel double weight-based synthetic aperture radar (SAR) and infrared (IR) sensor fusion method (DW-SIF) for automatic ground target recognition (ATR). IR-based ATR can provide accurate recognition because of its high image resolution but it is affected by the weather conditions. On the other hand, SAR-based ATR shows a low recognition rate due to the noisy low resolution ...
