A novel VLSI architecture for real time operations of one-bit coded synthetic radar imaging data

Real time processing for SAR data is a very useful tool in civilian and military applications. However, in order to avoid resolution degradation, a very short time must be required for each single multiplication. This condition can be verified by using one-bit coded data and reference function: in fact, in this case operations can be performed by XNOR gates. In this paper, a VLSI architecture for real time one-bit processing is presented, and first performance tests are reported.
