Suppression of Side Lobes in Radiation Patterns of Short-Pulse Radiating Systems

  • Published:
Radiophysics and Quantum Electronics Aims and scope

We show that the radiation patterns of two-dimensional systems in the form of arrays depend on the duration of the emitted pulses. To study such systems, we propose to use the correlation length depending on the pulse duration and the emission direction. The obtained formula for the length of correlation in two-dimensional systems is convenient for description of distortions in the radiation patterns, which are caused by shortening the duration of the emitted pulses. In this paper, we consider the effect of suppression of side lobes in radiation patterns. This is a general effect, since it is related to the delay of signals from different parts of the emitting system. In particular, it is observed in optical systems of the diffraction grating type, in which a decrease in the intensity of diffraction maxima in the case of pulse duration shortening can be used as the basis for a new method of estimation (or measurement) of the duration of optical pulses.
