摘　　要：针对TD-LTE下行信号与脉冲雷达引信信号可能在S波段2 300~2 400 MHz频段内产生干扰的问题,运用计算脉冲雷达引信接收机处信干比的方法,得出在其他因素确定的情况下,TD-LTE下行信号对脉冲雷达引信不产生干扰的隔离距离。并通过链路级仿真的办法验证了结论的正确性,同时还得出当两者之间的水平距离为隔离距离时,增大基站的发射功率(或者减小引信发射功率)、减小地面有效反射面积,引信同样会受到TD-LTE下行信号干扰的结论。Concerning that the TD-LTE downlink signal and pulse radar fuze signal may be interfered within 2 300 to 2 400 MHz band of S-band, the method of calculating the signal-to-interference ratio at the pulse radar fuse receiver was used. And the isolation distance that the TD-LTE downlink signal did not interfere the pulse radar fuze signal under the condition of other factors determined was obtained. The validity of the conclusion through the link level simulation was verified. At the same time, it was also obtained when the horizontal distance between the two was isolated distance, the transmission power of the base station was increased （or the fuze transmission power was reduced）, the grotmd effective reflection area was reduced, the fuse will also be interfered by TD-LTE downlink signal.
