SNR Gain Due to Azimuth Processing (coherent pulse integration)

The SNR Gain Due to Azimuth Processing calculator computes the gain based on the number of pulses integrated and 

INSTRUCTIONS: Enter the following:

• (N) Total Number of Pulses Integrated
• (L_a) Reduction in SNR gain due to non-ideal azimuth filtering

SNR Gain (G_a): Gain is returned in decibels.

The Math / Science

The formula used for SNR Gain in this calculator is:

         G_a = N / L_a

where:

• Ga = SNR Gain Due to Azimuth Processing
• N = Total number of Pulses Integrated
• La = Reduction in SNR gain due to non-ideal azimuth filtering

This equation calculates the SNR gain due to azimuth processing (coherent pulse integration)^{Signal-to-Noise of a Synthetic Aperture Radar.}
