Convert azimuth and elevation angle to broadside angle

## Syntax

``bsang = az2broadside(az)``
``bsang = az2broadside(az,el)``

## Description

example

````bsang = az2broadside(az)` returns the broadside angle, `bsang`, corresponding to the azimuth angle, `az`, and zero elevation angle. All angles are define with respect to the local coordinate system.```

example

````bsang = az2broadside(az,el)` also specifies the elevation angle, `el`.```

## Examples

collapse all

Return the broadside angle corresponding to 45° azimuth and 0° elevation.

`bsang = az2broadside(45)`
```bsang = 45.0000 ```

Return the broadside angle corresponding to 45° azimuth and 45° elevation.

`bsang = az2broadside(45,45)`
```bsang = 30.0000 ```

Return broadside angles for 10 azimuth-elevation pairs.

```az = (75:5:120)'; el = (45:5:90)'; bsang = az2broadside(az,el);```

## Input Arguments

collapse all

Azimuth angle, specified as a scalar or vector of real values. Azimuth angles lie in the range from –180° to 180°. Units are in degrees.

Example: `[35;20;-10]`

Elevation angle, specified as a scalar or vector. The elevation angle lie in the range from –90° to 90°. The length of `el` must equal the length of `az`. Units are in degrees.

Example: `[5;2;-1]`

## Output Arguments

collapse all

Broadside angle, returned as a scalar or vector. The length of `bsang` equals the length of `az`. Units are in degrees.

Broadside angles are useful in describing the response pattern of a uniform linear array (ULA).

For the definition of the broadside angle and how to convert between azimuth and elevation, and broadside angle see Broadside Angles. For definitions of the azimuth and elevation angles, see Azimuth and Elevation Angles.
