# sarmaxcovrate

Upper bound on area coverage rate for SAR

## Syntax

``acr = sarmaxcovrate(azres,grazang)``

## Description

example

````acr = sarmaxcovrate(azres,grazang)` returns the upper bound on area coverage rate based on SAR constraints.```

## Examples

collapse all

Estimate the constraint on area coverage rate of a side-looking airborne SAR. The radar has a cross-range resolution of 1.5 m and a nominal grazing angle of ${30}^{\circ }$.

```azres = 1.5; grazang = 30;```

Compute the area coverate rate constraint.

`coverage = sarmaxcovrate(azres,grazang)`
```coverage = 2.5963e+08 ```

## Input Arguments

collapse all

Image azimuth or cross-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

Upper bound on area coverage rate in square meters per second, returned as a matrix. The rows of `acr` correspond to the azimuth resolution values in `azres`. The columns of `acr` correspond to the grazing angle values in `grazang`.
