Radar Range Calculator

Radar Range Calculator calculator can be used to determine the distance a radar signal travels based on the round-trip time of the signal.

Input Parameters

Calculation Results

Calculation Formula

Range = (Speed of Light × Round-Trip Time) / 2

Where:
Speed of Light = 3 x 10⁸ meters per second
Round-Trip Time = Time taken for signal to travel to target and back (seconds)

Result

Calculated Range: -- meters

Learn how to use the Radar Range Calculator calculator and its working principles

How to Use This Calculator

  1. Enter the Round-Trip Time in seconds. This is the time it takes for the radar signal to travel to the target and back.
  2. Click the Calculate button to compute the radar range.
  3. The result will be displayed in meters.
  4. Use the Reset button to clear all inputs and start over.

Working Principle

Radar (Radio Detection and Ranging) systems work by emitting radio waves and measuring the time it takes for the waves to reflect off a target and return to the radar antenna. Since the waves travel at the speed of light, the round-trip time can be used to calculate the distance to the target.

The formula used in this calculator is:

Range = (Speed of Light × Round-Trip Time) / 2

Example

If the round-trip time for a radar signal is 0.0001 seconds (0.1 milliseconds), the calculated range would be:

Range = (3 × 10⁸ m/s × 0.0001 s) / 2 = 15,000 meters = 15 kilometers

This means the target is 15 kilometers away from the radar system.
