main lobe वाक्य
उदाहरण वाक्य
मोबाइल
- The main lobe of the antenna can be steered electronically within a limited angle by phase shifting the drive signals applied to the individual elements.
- The advantage of the Hann window is very low aliasing, and the tradeoff is slightly decreased resolution ( widening of the main lobe ).
- This reduces radar sensitivity at certain radial velocities, but MTI allows the main lobe of the antenna beam to be aimed closer to the ground.
- In all cases, the close-in sidelobe levels are consistently high, at about-13.5 dB relative to the main lobe.
- However, the various windowing functions do perform differently from one other, with some giving main lobes which are unnecessarily broad for the sidelobe levels achieved.
- There is also usually a backlobe, in the opposite direction to the main lobe, due to the spillover radiation from the feed antenna that misses the reflector.
- The radiation pattern is unidirectional, with the main lobe along the axis perpendicular to the elements in the plane of the elements, off the end with the directors.
- While settlements within the main lobe receive enough energy, the energy received by the settlements between the main lobes may be "'6 dB "'less.
- While settlements within the main lobe receive enough energy, the energy received by the settlements between the main lobes may be "'6 dB "'less.
- When different delay and sum beamformers are applied to each frequency bin, the result is that the main lobe simultaneously points in multiple different directions at each of the different frequencies.
- The antenna's main lobe, its direction of greatest sensitivity, is to the right, off the end of the wire that is terminated in the resistor . ]]
- "' Null fill "'is used in radio power away from the main lobe and electrically direct more of it at a more downward angle in the vertical plane.
- The main lobes that are involved in decision making and complex thought processes are undergoing their final development phase during adolescence and binge drinking can negatively stunt the growth of these frontal lobes.
- Therefore loudspeaker designers try to make the main lobe as fat as possible, by using drivers that are as small as possible in diameter so as to allow closer spacing between them.
- The main aims of most investigations into pulse compression has been to obtain narrow main lobes, with low sidelobe levels, a tolerance to Doppler frequency shifts and to incur low system losses.
- For example, a satellite antenna may not receive noise contribution from the earth in its main lobe, but sidelobes will contribute a portion of the 290K earth noise to its overall noise temperature.
- The concepts of main lobe and sidelobes also apply to acoustics and optics, and are used to describe the radiation pattern of optical systems like telescopes, and acoustic transducers like microphones and loudspeakers.
- Other metrics that can be seen are the width of the main lobe and the peak level of the sidelobes, which respectively determine the ability to resolve comparable strength signals and disparate strength signals.
- When resistor-terminated, the radiation pattern is unidirectional, with the main lobe off the terminated end, so this end of the antenna is oriented toward the target country or geographical region.
- The radiation pattern referred to above is usually the horizontal radiation pattern, which is plotted as a function of azimuth about the antenna, although the vertical radiation pattern may also have a main lobe.
