High-resolution and real-time inverse synthetic aperture imaging based on a broadband microwave photonic radar

A microwave photonic radar system with optical generation and de-chirping processing of broadband linear frequency modulated continuous-wave signal is proposed for high-resolution and real-time inverse synthetic aperture radar (ISAR) imaging. A K-band microwave photonic radar prototype is established and the ISAR imaging feasibility is experimentally investigated. The imaging results verify that the proposed radar works well and is hopefully to find wide applications where high-resolution and real-time radar imaging is required.
