# grnd2slantrngres

Convert ground range resolution to slant range resolution

## 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.
