# Array Factor Calculator & AF Pattern Plot
## Installation
```pip install arrayfactor==1.0.3```
## Modules
The **arrayfactor** library enables to calculate the normalized array factor values
in the range of -180 to 180 degree with respect to the array factor input
variables which are: Inter-element spacing,frequency,steering angle,
number of array elements,plane.
The six main modules of the package are:
* ```af.af_asym_phasescannig``` : To get Array Factor of Uniform or Asymmetrically Spaced Arrays with Phase Shifting Technique
* ```af.af_asym_timescannig``` : To get Array Factor of Uniform or Asymmetrically Spaced Arrays with True Time Delay Technique
* ```af.af_symmetrical_phasescannig``` : To get Array Factor of Symmetrically Spaced Arrays with Phase Shifting Technique
* ```af.af_symmetrical_timescannig``` : To get Array Factor of Symmetrically Spaced Arrays with True Time Delay Technique
* ```af.cartesian_plot``` : To get Array Factor Pattern on 2D Cartesian plot
* ```af.polar_plot``` : To get Array Factor Pattern on 2D Polar plot
## Description of Input Variables
* af.af_asym_phasescannig(```bx```,``` by```, ```bz```, ```f```, ```f0```, ```steering_angle```, ```Nx```, ```Ny```, ```Nz```, ```increase_rate```, ```plane```)
* af.af_asym_timescannig(```bx```,``` by```, ```bz```, ```f```, ```f0```, ```steering_angle```, ```Nx```, ```Ny```, ```Nz```, ```increase_rate```, ```plane```)
* af.af_symmetrical_phasescannig(```bx```,``` by```, ```bz```, ```f```, ```f0```, ```steering_angle```, ```Nx```, ```Ny```, ```Nz```, ```increase_rate```, ```plane```)
* af.af_symmetrical_timescannig(```bx```,``` by```, ```bz```, ```f```, ```f0```, ```steering_angle```, ```Nx```, ```Ny```, ```Nz```, ```increase_rate```, ```plane```)
* af.cartesian_plot(```x_axis```, ```y_axis```)
* af.polar_plot(```x_axis```, ```y_axis```)
* ```bx``` : The coefficient represents the association of distance between elements along x axis and wavelength (dx=bx*lambda)
* ```by``` : The coefficient represents the association of distance between elements along y axis and wavelength (dy=by*lambda)
* ```bz``` : The coefficient represents the association of distance between elements along z axis and wavelength (dz=bz*lambda)
* ```f``` : Frequency of the signal sent.
* ```f0``` : Center Frequency.
* ```steering_angle``` : It is desired beam steering angle. It must be written in degree.
* ```Nx``` : Total number of elements along x axis
* ```Ny``` : Total number of elements along y axis
* ```Nz``` : Total number of elements along z axis
* ```increase_rate``` : This is the amount of change of distance between two successive elements in the case of NON-UNIFORM ASYMMETRICAL OR NON-UNIFORM SYMMETRICAL spacing.
**Note:** For uniform array, ```af.af_asym_phasescannig``` or ```af_asym_timescannig``` must be used and ```increase rate``` must be set as 0.
For the further information about it, please refer to the link: https://github.com/Barkhausen-Institut/AntennaArraySimulator/blob/master/ArrayFactorUserInterface/Theory%20of%20Array%20Factor.pdf
* ```plane``` : It decides if the results are obtained on E or H plane. 'E' or 'H' must be written.
* ``` x_axis``` : Values of x axis of the plot.
* ``` y_axis``` : Values of y axis of the plot.
## Outputs of Modules
Output of aforementioned functions (modules) is consisting of two Numpy arrays:\
1-First element (array) contains the values of incident angle as range from -180 to +180 degree.\
2-Second element (array) contains the values of normalized array factor.
## Examples of Usage
**Example 1:** Get the normalized array factor values of 16 elements broadside uniform linear array along x- axis (spacing based on half wavelength) at 10 GHz on E plane.
```
from arrayfactor import af
result=af.af_asym_phasescannig(0.5,0,0,10e9,10e9,0,16,1,1,0,'E')
#To get Cartesian Plot:
af.cartesian_plot(result[0], result[1])
#To get Polar Plot:
af.polar_plot(result[0], result[1])
```
**Example 2:** Get the normalized array factor values of 8 elements symmetric linear array with the increase rate=0.1 along x- axis (spacing based on half wavelength) at 10 GHz on E plane and with 30° beam steering angle (by TTD technique).
```
from arrayfactor import af
result=af.af_symmetrical_timescannig(0.5,0,0,10e9,10e9,0,16,1,1,0.1,'E')
#To get the Cartesian Plot:
af.cartesian_plot(result[0], result[1])
#To get Polar Plot:
af.polar_plot(result[0], result[1])
```
