Abstract
How to effectively eliminate interference targets existing in secondary radar and improve equip-ment processing capability and effectiveness is the orientation of system design concerned. Different from the traditional method of simple channel receiver sensitivity adjustment,this paper proposes a method of re-al-time calculation of the target response intensity based on Field Programmable Gate Array( FPGA) . By setting the effective response signal range and eliminating the multipath and asynchronous interference pul-ses outside the Sensitivity Time Control( STC) threshold in reply pulse processing stage,the amount of in-formation data is reduced,the system efficiency and multi-target processing capability are improved. Field test shows that this method can effectively reduce 70% of the false targets in the secondary radar systems.关键词
