One example is, an X-band frequency of eight.5GHz will likely have a wavelength of 35.2mm. 50 % this wavelength is seventeen.6mm. Chaff dipoles would want for being this duration to jam a radar transmitting on eight.
That, in turn, alters the nature on the echo, and the electronics in the Management box can interpret the improve and reveal the probably id on the metal—all of them respond otherwise on the electromagnetic industry, yielding distinctive echoes. (That said, the interpretation is much from actual: The depth, measurement, and orientation of an item can all adjust how the machine “reads” it. In my encounter, aluminum pull tabs often registered at frequencies that could have indicated silver or copper.
