Description
Return ideal uncompressed radar range resolution.
Radar and lidar measurements combine propagation distance, pulse/gate geometry, background and instrument response. A local range or normalization term can be useful without detecting a target, retrieving atmospheric properties or establishing calibrated sampling resolution.
Return ideal uncompressed radar range resolution.
When to use this tool
Use Radar Range Resolution Pulse Width Term when checking the stated radar/lidar geometry, signal or transmission convention.
How to use the tool and how it works
- Enter pulseSeconds, propagationSpeed. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read rangeResolution. Use the output convention below.
Return ideal uncompressed radar range resolution. Require pulseSeconds >= 0 and propagationSpeed > 0; rangeResolution = pulseSeconds*speed/2.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| pulseSeconds | Pulse Seconds | Required. Finite number; minimum 0. |
| propagationSpeed | Propagation Speed | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| rangeResolution | Range Resolution | Required. Finite number. |

}Limitations and assumptions
- The half factor is for round-trip propagation; bandwidth/pulse compression, beam geometry and real target resolvability are omitted.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified instrument calibration and a complete appropriate retrieval/response model, including geometry and signal uncertainty, for actual remote-sensing conclusions.
