Abstract

The operation and processing for an airborne scan mode patch-mapping synthetic aperture radar (SAR) system are discussed, which serves for moderate fine-resolution mapping of medium-sized terrain patches. The scanning angular scope and velocity are determined by the desired imagery patch size and cross-range resolution respectively. The linear range-Doppler algorithm is employed in image formation. Finally, the experimental result of the test campaign of the described system is also presented in the paper.
