Abstract
For the distributed targets arising in most synthetic aperture radar (SAR) images, it is the integrated sidelobe (ISL) energy rather than the peak sidelobe level (PSL) that governs the performance of the pulse compression processing. A sidelobe cancellation technique is suggested which reduces the ISL energy by eliminating a significant portion of the sidelobe pattern of the pulse compression output, while the PSL is presented at the optimal Barker-code level. The efficiency of this ISL reduction is proportional to the signal code length
