摘要
针对某毫米波探测器研制的需求,介绍了所设计的ADPCI2002,实现了对雷达回波信号模拟与采集。着重讨论了大容量数据缓存的实现、模拟外触发电路的实现、用突发方式来实现PCI总线的高速数据传送、信号模拟时的滤波问题以及板级的信号完整性设计等问题。实测结果表明,该设计工作稳定正常,能够实现对步进频率、调频步进、脉冲多普勒等雷达信号的模拟与数据采集。
ADPCI2002 card is introduced, aiming at the demand of some millimeter wave (MMW) guidance. Simulation and acquisition of radar echo signal is realized. Emphases are placed on how to configure huge data buffer, how to implement analog exoteric trigger, how to transmit data throughout PCI bus by means of burst mode, filtering and signal integrality design for the whole board. The design is tested, and the result shows it can simulate and acquire some radar echo signals such as SF, MFSF or PD radar signals.
