Any deviation in the course of the seeker control loop will make the body attitude angle couple into the LOS rate output, because the missile will be subject to airflow, disturbance torque in the flight process, thereby affecting the stability and tracking of the radar seeker beam axis
and reducing the missile guidance accuracy [19-22].
The total displacement at any given point of the section is related to the beam axis
The calculations are in good agreement with measurements on the neutron beam axis
for the 43-MeV p-[sup.7]Li neutron source with up to 25% discrepancy, as shown in Table 2.
All 4 radars are able to capture and describe the "27-day" variability of the microwave signal emitted by the Sun; the DRAO reference curve, which refers to accurate 1-hour-long daily measurements with the antenna radiation pattern beam axis
hitting the center of the disk, is obviously much smoother than radar daily estimates, which are retrieved by fitting tens of off-axis hits acquired during a fraction of a second.
The authors developed a program in MATLAB that performs the calculation of (11) and (12) depending on the orientation of the body frame relative to the orbital frame and angle of the ion beam axis
Nevertheless, the photon fluence appears to decrease as we move further away from the beam axis
, since the thickness decreases with the distance of the axis of the beam due to the geometry of the flattening filter.
TBM constitutes an improvement over EBBM since the cross-section does not necessarily remain perpendicular to the beam axis
after deformation and one degree of freedom (i.e., the unknown rotation [[phi].sub.Z]) is added to the original displacement field (see Figure 2(b)).
"In radiography, if a defect's orientation is more than 8[degrees] in relation to the beam axis
the defect is unlikely to be detected," says Richards.
A rigid arm is placed between the deviator and the beam axis
, while the rubber element, which can adjust the frictional coefficient between external tendon and deviator, is set in the node between the rigid arm and beam axis
In order to determine the process function HV, hardness was measured in several characteristic points, that is in the points [a.sub.0], b and c located on the beam axis
and, respectively, in symmetrical points [a.sub.s1], [a.sub.d1], [a.sub.s2], [a.sub.d2] and [b.sub.s], [b.sub.d], [c.sub.s] and [c.sub.d], represented in figure 1.
For 100% efficiency, detector modules are consecutively placed along the beam axis
. Analysis over several regions with alternating wire strip orientation provides a two-dimensional beam profile.
The magnitude and phase of received RF energy each feedhorn receives varies according to the position and vector velocity of the target relative to the beam axis
. The received beams include a sum channel, a difference signal between the upper and lower halves of the antenna, and another difference signal between the left and right halves of the antenna.
