摘要
针对模拟体制脉冲应答机中声表面波延迟线的设计缺陷,运用基于FPGA的数字存储转发技术,提出一种数字化高精度时延补偿方法,大大提高了脉冲应答机的时延转发精度。该脉冲应答机具有延迟时间易修改、转发精度高等特点,对实际工程应用具有借鉴价值。
Due to the design weakness of the delay line of anolog Surface Acoustic Wave Filter（SAWF） in analog pulse transponder, a digital time delay compensation method with high precision is proposed based on digital store and forward（SAF） technique of FPGA, which improves time delay transmitting precision of the transponder. The pulse transponder has such merits as easily modified time delay, high transmitting precision. This method is of great benefit to some projects.
