Spotlight SAR Sensor Model Supporting Precise ...

Eq. 7 Where : two-way 3dB angular beam width. D: antenna size in the cross-range direction (: transmitted wavelength. Ka: excess bandwidth factor due to antenna weighting (Ka=0.886 for uniform illumination) We’ll take this opportunity to tie this discussion to the imaging problem. Imagine we’re using the antenna to measure the response from ... ................
