摘要: 該文介紹的預處理板,是根據(jù)機載L-SAR實用系統(tǒng)的技術要求設計完成的。它采用AD公司的最新高速數(shù)字處理芯片ADSP21062來實現(xiàn)預處理功能。采用這種方法研制的預處理板,預濾波比可以根據(jù)不同的需要靈活地改變,運算精度也大大地提高。本文詳細介紹了預處理器的原理及實現(xiàn)。Abstract: 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.
