Grating effect
WebGrating lobes are undesirable and identical to the main lobe. The perceived difference seen in the grating lobes is because of the radiation pattern of non-isotropic antenna elements, which effects main and grating lobes differently. For isotropic antenna elements, the main and grating lobes are identical. Definition [ edit] Webchirp of the input spectrum is then required to estimate what the effect of the grating compressor will be. In case this chirp is known (for example via a FROG or SPIDER measurement, or simply from a numerical estimation), one simply needs to use (4) to find the grating configuration that exactly compensates for this chirp. - 6 -
