# grnd2slantrngres

Convert ground range resolution to slant range resolution

## Syntax

``slrngres = grnd2slantrngres(grndrngres,grazang)``

## Description

example

````slrngres = grnd2slantrngres(grndrngres,grazang)` returns the slant range resolution `slrngres` corresponding to the ground range resolution `grndrngres` and the grazing angle `grazang`.```

## Examples

collapse all

Determine the slant range resolution given a ground range resolution of 1 m and a grazing angle of 30${}^{\circ }$.

```grndrngres = 1; grazang = 30;```

Compute the slant range resolution.

`slrngres = grnd2slantrngres(grndrngres,grazang)`
```slrngres = 0.8660 ```

## Input Arguments

collapse all

Ground range resolution in meters, specified as a positive real scalar or a vector.

Data Types: `double`

Grazing angle in degrees, specified as a scalar in the range [`0`, `90`] or a vector.

Data Types: `double`

## Output Arguments

collapse all

Slant range resolution in meters, returned as a matrix. The rows in `slrngres` correspond to the ground range resolutions in `grndrngres` and the columns correspond to the grazing angles in `grazang`.
