time2range

Convert propagation time to propagation distance

Syntax

r = time2range(t)

r = time2range(t,c)

Description

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)

r = 
2.9979e+05

Input Arguments

t — Propagation time

array of positive numbers

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

c — Signal propagation speed

speed of light (default) | positive scalar

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

Data Types: double

Output Arguments

r — Propagation distance

array 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.
