Pulse Width Calculator

Pulse Width helps you calculate design values for a radar engineering project from Desired Range Resolution. Calculate the radar pulse width required to achieve a specified range resolution for a pulsed radar system. Use the result to make an informed first design decision before choosing hardware, setting dimensions, or evaluating the RF system in its final environment.

Enter Desired Range Resolution exactly in the units shown by this pulse width. Check the operating band, unit prefix, and decimal position before calculating; these are the inputs used by the formula.

• Desired Range Resolution — use m.

The results describe the calculated pulse width values for the inputs you entered. Check each value against the available space, selected components, feed system, and operating conditions before making a final design decision.

The Pulse Width uses τ = 2ΔR/c, B ≈ 1/τ. Supply Desired Range Resolution (m) in the displayed units, then use the calculated values as the first engineering target for this radar engineering design or analysis.

This radar engineering calculation is based on τ = 2ΔR/c, B ≈ 1/τ. Real-world accuracy depends on factors such as material properties, losses, mounting, nearby conductors, ground interaction, feed-line effects, and construction tolerance. Confirm the final system with measurement or simulation.

Apply the pulse width result as an initial target, then validate it in the intended installation. Keep the physical layout and feed arrangement consistent while testing, change one parameter at a time, and record the measured outcome before making another adjustment.
