SAR Duty Factor

The SAR Duty Factor calculator computes duty factor for a mono static synthetic aperture radar based on the pulse frequency and the time between pulses.

INSTRUCTIONS: Choose units and enter the following:

• (T_eff) Effective Pulse Width (time separation)
• (f_p) Pulse Frequency

SAR Duty Factor (d): The factor is returned as a real.

The Math / Science

This equation calculates the duty factor^{Signal-to-Noise of a Synthetic Aperture Radar.}
