Appendix A — Resolution calculator

Slant-range resolution from waveform bandwidth, its ground projection from incidence angle, and azimuth resolution from the aperture. All figures derive live from the inputs.

Center frequency — GHz

Bandwidth — MHz

Incidence angle — deg

Azimuth mode

Antenna length — m

Derived figures

Wavelength 3.12 cm

Slant-range resolution 25.0 cm

Ground-range resolution 35.3 cm

Azimuth resolution 1.50 m
