摘　　要：在某RCS测试系统中,为录取试验现场的实测数据,建立了针对雷达RCS参数的试验数据库。设计实现了一个基于标准PCI总线、高速ADC和高性能DSP的数据采集预处理模块。论述了测算RCS的原理、数据录取率的估算、板卡的硬件实现以及上位机的软件开发等内容。该数据采集预处理模块在系统测试过程中工作稳定,满足了预期的设计要求。由于板卡硬件设计考虑到了通用性,使得该模块可以方便地应用于其它一些具有高数据吞吐量及一定数字信号处理工作量的场合。In order to build a database for radar's basal element —— RCS, the data of the field experiments in RCS measuring system need to be recorded. A design of a data acquisition and pre-processing module is realized based on the PCI standard bus, high-speed ADC and high performance DSP is introduced. The RCS computation principles, the data amount estimation, the hardware realization and the relative software development are included in this paper. The module has been proved to be stable in working and meets the design requirements. Because of taking the general-purpose usages into consideration in the design phase, this module can be also easily used in some other applications needing high data throughout ability and some digital signal processing ability.;
