Synthetic Aperture Radar Processing Approach for Simultaneous Target Detection and Image Formation
Sensors, 2018 Finding out interested targets from synthetic aperture radar (SAR) imagery is an attractive but challenging problem in SAR application. Traditional target detection is independent on SAR imaging process, which is purposeless and unnecessary. Hence, a new

Wafer‐Scale Top‐Down Patterning of Metal Halide Perovskites
Advanced Materials Technologies, EarlyView.Wafer‐scale patterning of metal halide perovskite films is demonstrated on 150 mm substrates using a chemically amplified resist, polymethyl methacrylate (CAR‐PMMA) and a single reactive ion etching step. The streamlined process preserves film luminescence while defining submicrometer features across the full wafer, enabling dense, scalable integration
