The approximate theory of radar reflection from thin wires by Van Vleck, et. al., gives very good average radar cross section RCS results and good angular RCS results except end-on. In the paper, the nature of this end-on discrepancy is examined. It is found that, if the complete expressions derived by Van Vleck, et. al., are used without the approximations made to simplify calculation of the average RCS over all angles of incidence, then very accurate RCS results are predicted for nearly all angles of incidence and for all the wire length-to-wavelength ratios between 0.45 and 50. Comparisons with the numerical results of a source distribution technique SDT computer program and with the results due to Ufimtsev are shown.
