花生米怎么炒摘要：The invention of this disclosure compris a system that simultaneously determines the frequency and direction of arrival of incoming signals. The apparatus of this invention compris a layered half space dispersive delay line which is utilized as a beam forming element in a device that performs a two-dimensional Fourier transform on a function which is both time and space dependent.
A pul appears at the end of the delay line at a time which corresponds to the frequency of the incoming signal and the position of the pul along the edge of the delay line is related to the direction of arrival of the incoming signals.
