Corrections to “A Novel Elliptical-Cylindrical Antenna Array for Radar Applications” [May 16 1681-1688

Abstract

In [1, p. 1683], in the line one below (4), $P_{n} $ is undefined and should be distinguished from $P_{n} $ in line four at p. 1682. In the sentence one below (4), some statements are incorrect and redundant. The corrected expression of that sentence should be “we can have the maximum possible radiation pattern when $p_{m} =-K\cdot d\cdot \cos (\theta _{0} )$ and $p_{n} =-K\cdot \sin (\theta _{0} )(a\cdot \cos (\phi _{n} )\cdot \cos (\phi _{0} )+b\cdot \sin (\phi _{n} )\cdot \sin (\phi _{0} ))$ .” And in line 7 after (4), $\vartheta $ is undefined and $\vartheta $ should be correct to $\theta $ . Equation (5) is incorrect. The correct equation follows: \begin{equation*} F_{\mathrm{ Hyper}} = \big \{{ ( { | {F_{\mathrm{ Left}}} |+ | {F_{\mathrm{ Right}}} |} )^{k}- ( { | {F_{\mathrm{ Left}} -F_{\mathrm{ Right}}} |} )^{k}} \big \}^{\frac {1}{k}}.\tag{5}\end{equation*}
