Total radar cross section of thin wires at all angles of incidence

摘要

The total radar cross section (RCS) of thin perfectly conducting wires is calculated by two methods using the general Van Vleck, Bloch, and Hamermesh theory of RCS. These methods involve calculating the work done on the wire by the incident field or calculating the total flux scattered by the wire. It is found the two methods give nearly identical results and it is suggested that the method of work be used due to its simpler formulation. Numerical examples are presented and it was observed that resonances in the broadside total RCS occur at halfhyphen;integer values of bgr;l, where bgr; is the propagation vector andlis onehyphen;half the wire length.
