Radar Range Resolution Calculator

This calculator helps determine the range resolution of a radar system based on its signal bandwidth. Radar range resolution is the minimum distance between two targets that can be distinguished in the range dimension.

Calculation Formula

Range Resolution (R) = (c / (2 * B))

Where:
c = Speed of light (3 x 10^8 m/s)
B = Bandwidth of radar signal (Hz)

What is Radar Range Resolution?

Radar range resolution is the ability of a radar system to distinguish between two targets that are separated by a certain distance in the range dimension. It is typically expressed in meters and represents the minimum distance at which two targets can be resolved as separate entities.

How to Use This Calculator

  1. Enter the radar signal bandwidth in Hz. This is typically provided in the radar system specifications.
  2. Click the "Calculate" button to compute the range resolution.
  3. The result will be displayed in meters.

Principle Behind the Calculation

The formula used for calculating radar range resolution is based on the relationship between signal bandwidth and the ability to resolve targets in range. A wider bandwidth generally results in better range resolution.

Practical Applications

Radar range resolution is a critical parameter in radar system design and performance evaluation. It affects various aspects of radar operation including:

  • Detection of closely spaced targets
  • Resolution of ground clutter
  • Tracking of multiple targets
  • Mapping applications

Example

If a radar system has a bandwidth of 10 MHz (10,000,000 Hz), the range resolution would be:

R = (3 x 10^8 m/s) / (2 * 10,000,000 Hz) = 15,000 meters or 15 kilometers
