Sector imaging radar for enhanced vision [PDF]

Aerospace Science and Technology, 2003
Summary: SIREV (sector imaging radar for enhanced vision) is an innovative airborne radar system which can supply high-quality images in any desired direction under almost every weather condition. In contrast to synthetic aperture radar systems, no relative motion between sensor and targets is required in SIREV.

Broadband LFM Radar Imaging System Based on Microwave Photonic I/Q De-chirping

Leida xuebao, 2019
We propose a novel scheme of broadband LFM radar imaging system based on microwave photonic I/Q de-chirping. In the transmitter, a broadband linear frequency modulated signal is generated by photonic frequency-doubling.
