Abstract: An input sampling method includes the following: acquiring a first pulse signal and a second pulse signal respectively; widening a pulse width of the first pulse signal to obtain a widened first pulse signal; shielding an invalid signal in the second pulse signal based on the widened first pulse signal to obtain a to-be-sampled signal; and finally, sampling the to-be-sampled signal based on a clock signal. In this way, prior to signal sampling, the invalid signal is shielded to avoid additional power consumption caused by sampling the invalid signal, and at the same time, the pulse width of the signal is widened to avoid sampling failure.

Abstract: Disclosed is a shaped horn in conjunction with a dielectric tube for enhanced aperture directivity that can achieve a near optimum efficiency. The shaped horn provides additional mode control to provide an improved off-axis cross-polarization response. The horn shape can be individually optimized for isolated horns or for horns in a feed array. The feed array environment can produce results that lead to a different optimized shape than the isolated horn. Lower off axis cross-polarization can result in improved efficiency and susceptibility to interference.
