There are no fluctuations along the diagonal, which means that the antenna array gain is constant with respect to the aiming angle. This is a clear demonstration of the fact that by circulating one waveform through the transmitting radar channels, the orthogonality of the radiated signals can be achieved.
Figure 5 shows another cut of the ambiguity function [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] obtained by means of the signal processing for the aiming angle [[theta].sub.0] = 30[degrees] in one of the receiving channels.
Even when a gun is fired in a mountainous area, the aiming angle is relatively small; the velocity component [V.sub.0y] < 330 m/s and the system of equations describing the movement of the projectiles is as follows:
When one is shooting at objects located in a lower position, the aiming angles are equal to several degrees (Fig.
All fixtures offer vertical aiming angle
adjustment (0 to 90 degrees), as well as locking, to maintain aiming position and allow the lighting to remain consistent.
"We conducted a lot of studies to determine the opening and depth of the slots," says McKnight, "and to ensure that the merchandise could be lit properly at comfortable aiming angles for the customers."
"The previous approach had MR16s, and a variety of lamps, aiming angles and locations.
Selecting the proper pole locations and fixture aiming angles
depends on many factors.
"That was our only mounting option, which made it difficult to achieve ideal aiming angles
," says Rizzo.
"We developed this solution to address the requirements of aiming angles
, and to provide easy and safe access."
To determine where best to lay the track, the team worked backwards from the aiming angles
, which ensured that light was cast exactly where it was needed.
