directivity

difference between the A-weighted sound pressure levels measured at different measurement positions and this measured at a reference position downwind from the turbine corrected to the same distance from the wind turbine generator system rotor center NOTE 1 - The directivity is expressed in decibels. NOTE 2 - The reference and measurement positions...

directivity

the ratio, generally expressed in decibels, of the radiation intensity produced by an antenna in a given direction, to the value of the radiation intensities averaged in all directions in space NOTE 1 - If no direction is specified, the direction of maximum radiation intensity from the given antenna is implied. NOTE 2 - The directivity is independe...

directivity

the ratio, usually expressed in decibels, of the power output measured at the appropriate port of one of the transmission lines of a directional coupler, when power is fed into the other transmission line in the preferred direction, to the power output measured at the same place when the same power is fed into the same line in the opposite directio...

directivity

The ratio of the maximum sensitivity of an antenna to its average sensitivity. It varies directly as the effective aperture of the antenna and inversely as the square of the wavelength.

Directivity

==Accounting for polarization== When polarization is taken under consideration, three additional measures can be calculated: ===Partial directive gain=== Partial directive gain is the power density in a particular direction and for a particular component of the polarization, divided by the average power density for all directions and all polarizat...
