The Signal to Noise Ratio Gain due to Range Processing calculator computes the gain based on the effective pulse width, noise bandwidth and reduction in signal noise.

INSTRUCTIONS: Choose units and enter the following:

  • (Teff) Effective pulse width of the radar
  • (BN) Noise bandwidth at the antennae
  • (Lr) Reduction in signal to noise ratio gain due to non-ideal range filtering.

Signal to Noise Ratio Gain due to Range Processing (Gr):  The SNR gain is returned.

The Math / Science

The formula for the Signal to Noise Ratio Gain due to range processing (pulse compression) is:

   `G_r =   (T_(eff) * B_N)/L_r`

where:

This equation calculates the SNR gain due to range processing (pulse compression)1 for monostatic synthetic aperture radar.  This equation is most helpful in the context of calculating the Signal-to-Noise of a Synthetic Aperture Radar.
