BACKSCATTER FROM SPHERES: A SHORT PULSE VIEW

The backscatter from conducting and dielectric spheres, and to a lesser extent from conducting spheres with a relatively thin dielectric coating, is considered in the time domain. Utilizing rigorously computed values of the amplitude and phase of the continuous wave backscatter, short pulses of electromagnetic waves are synthesized by Fourier series. The resultant returns are examined as a function of time, and the individual returns compared with some approximate theories.
