# time2range

Convert propagation time to propagation distance

## Syntax

• `r = time2range(t)` example
• `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

### Minimum Detectable Range for Specified Pulse Width

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

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

## Input Arguments

collapse all

### `t` — Propagation timearray of positive numbers

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

### `c` — Signal propagation speedspeed of light (default) | positive scalar

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

Data Types: `double`

## Output Arguments

collapse all

### `r` — Propagation distancearray of positive numbers

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`.
