摘　　要：由于引信近距盲区精确测试的需要,设计了引信点目标视频回波模拟器距离模拟电路。该电路采用基于FPGA的时间数字转换(TDC)技术,在单片FPGA内将计数延时技术、TDC技术及精密数控延时技术相结合,对引信发射脉冲包络实现了大范围高分辨率精密数控延时,实现了优于±0.3 m的距离模拟精度。The distance simulation circuit for a wireless fusee target video frequency echo simulator has been designed based on TDC for the precision testing of the close quarters blind-area. The circuit combines with counter delay technology,TDC technology and precision digitally control delay technology. This plan has not only the high performance of the agility and high resolution, but also the larger range of the adjustment. The accuracy of distance simulation superior to 0.3 m is realized.
