# time2range

Convert propagation time to propagation distance

## Syntax

``r = time2range(t)``
``r = time2range(t,c)``

## Description

example

````r = time2range(t)` returns the distance a signal propagates during `t` seconds. The propagation is assumed to be two-way, as in a monostatic radar system.```
````r = time2range(t,c)` specifies the signal propagation speed.```

## Examples

collapse all

Calculate the minimum detectable range for a monostatic radar system where the pulse width is 2 ms.

```t = 2e-3; r = time2range(t)```
```r = 2.9979e+05 ```

## Input Arguments

collapse all

Propagation time in seconds, specified as an array of positive numbers.

Signal propagation speed, specified as a positive scalar in meters per second.

Data Types: `double`

## Output Arguments

collapse all

Propagation distance in meters, returned as an array of positive numbers. The dimensions of `r` are the same as those of `t`.

Data Types: `double`

## Algorithms

The function computes `c*t/2`.
