Dispersion of a wide-bandwidth radar signal by a static atmosphere is considered. Using experimental data to fit the attenuation in dbkm due to molecular resonances, the index of refraction may be inferred. The dispersive delay due to two-way propagation through the atmosphere is then compared to the dispersion one would normally design for a pulse compression receiver. Comparison indicates that atmospheric dispersion is quite small unless the center frequency is near the lowest water vapor resonance at lambda 1.35 cm.
