Interference analysis of TD-LTE downlink signal on S-band pulse radar fuse Abstract: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 ground effective reflection area was reduced,the fuse will also be interfered by TD-LTE downlink signal.
