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: Metasurfaces can alter radar echo characteristics by dynamically modulating the phase of incident electromagnetic waves, thereby degrading radar signal processing performance. Recovering the ...

Abstract: Utilizing periodic phase modulation (PPM) can shift the echo spectrum, affecting matched filtering (MF) processing, leading to time delay shift or amplitude attenuation. The prior works on ...
