1. What is Range Resolution?

Range Resolution is the ability of radar system to distinguish between two or more targets on the same bearing but at different ranges. It represents the minimum distance separation required between targets for the radar to identify them as separate entities.

2. How Does the Calculator Work?

The calculator uses the Range Resolution formula:

Where:

• \( \Delta R \) — Range Resolution (m)
• \( H_a \) — Antenna Height (m)
• \( H_t \) — Target Height (m)
• \( R_o \) — Range (m)

Explanation: The formula calculates the minimum resolvable distance between targets based on the geometry of the radar system and the target's position relative to the antenna.

3. Importance of Range Resolution

Details: Accurate range resolution is crucial for radar systems to effectively distinguish between multiple targets, provide precise target tracking, and avoid target merging in radar displays. It directly impacts the radar's performance in target identification and separation.

4. Using the Calculator

Tips: Enter antenna height, target height, and range in meters. All values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect range resolution?
A: Range resolution is primarily affected by antenna height, target height, and the distance between radar and target. Higher antenna and target heights generally improve resolution.

Q2: How does range resolution differ from angular resolution?
A: Range resolution deals with distinguishing targets at different distances, while angular resolution deals with distinguishing targets at different angles or bearings.

Q3: What are typical range resolution values in radar systems?
A: Range resolution varies significantly depending on the radar type and application, ranging from a few meters for long-range systems to centimeters for high-resolution radar.

Q4: Can range resolution be improved?
A: Yes, range resolution can be improved by increasing antenna height, using higher frequency signals, or employing pulse compression techniques.

Q5: What are the limitations of this formula?
A: This formula provides a basic geometric calculation and may not account for signal processing techniques, atmospheric conditions, or other factors that can affect actual radar performance.
