Abstract: Typically, synthetic aperture radar (SAR) uses linear frequency modulation (LFM) signal to acquire high-resolution images, requiring spectral windowing to suppress sidelobes while ...

Abstract: This paper proposes and demonstrates an arbitrarily tunable multi-frequency pulse modulation scheme based on an active fiber loop, which effectively suppresses the interference fading effect ...

Radio spectrum is pricey. Operators drop billions at auction to lock down licensed frequency bands, and every single frequency counts. Dynamic Spectrum Sharing (DSS) was built to address exactly this, ...

Background Genetic studies of stool frequency (SF), an indirect proxy for gastrointestinal transit, may reveal therapeutically tractable pathways relevant to IBS and other dysmotility disorders.
