Abstract: Typically, synthetic aperture radar (SAR) uses linear frequency modulation (LFM) signal to acquire high-resolution images, requiring spectral windowing to suppress sidelobes while ...
Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...
Abstract: Modern aircraft use 360–800 Hz variable-frequency power systems, and the increased frequency makes it more difficult to interrupt the arc. Traditional contacts are difficult to apply due to ...
