With the increase of k, the missile boresight error becomes smaller as can be seen in Figure 17, which reduces the requirement of missile attitude control acceleration in actual engagements [16].
In a dynamical process, oscillation causes the constantly changing of the missile boresight error [epsilon], as the black lines shown in Figure 17.
Thus, radomes can negatively affect the antenna performance by distorting the amplitude and phase in the main beam, bringing more sidelobes, boresight errors, and a decreased bandwidth [17].
The EM performance parameters (Co-pol power transmission, X-pol transmission, boresight error (BSE) etc.) of antenna-radome system are computed for antenna scan angles corresponding to window regions [R.sub.1], [R.sub.2], and [R.sub.3] based on 3D Ray-tracing procedure in conjunction with Aperture Integration method.
The azimuth boresight error of Inhomogeneous Dielectric Radome is higher than that of Monolithic Radome in the antenna scan range 0[degrees]- 15[degrees].
In the terminal guidance process, the boresight error [[psi].sub.c] approximately equals to tracking error, generally in the mil order.
Boresight errors are S-shaped curves about the axis through the nose of a tangent ogive radome, as used on missiles.
