%X This paper presents the design of pre-filter which can meet the requirements of airborne operational L-SAR system. Pre-filtering processing is carried out with the newest high-speed ADSP21062 chip from AD company. Pre-filtering ratio is changable according to difi'erent demands and the precision of calculation is improved in this design. In this paper, the principle and realization of pre-filter is introduced in detail.
