摘　　要：在直接序列扩频(简称直扩)体制抗干扰测试中,传统的抗干扰测试系统通常只涵盖了同频异码多址干扰与同频单载波干扰2种干扰信号,无法充分验证航天器测控通道的抗干扰能力。为此,文章提出一种适用于直扩体制的抗干扰通用化测试系统设计,将干扰信号的种类扩充至8种。同时,利用虚拟仪器与远程技术,实现对地面测试设备的集中式管理、程控与实时监视的功能,具备良好的人机交互能力。测试结果表明:抗干扰通用化测试系统具备干扰信号种类全面、通用性强的特点,能够提高测试效率,可应用于后续航天器测控通道抗干扰性能试验。In the anti-interference test of DSSS(direct sequence spread spectrum)system,traditional anti-interference test systems only identify two kinds of interference signals,which are the same-frequency-different-code multiple access interference and the same-frequency single-carrier interference,which can not be fully verified the anti-interference ability of spacecraft TT&C(tracking,telemetry and command)channel.For this reason,a universal anti-interference test system for DSSS system is proposed in this paper,which enriches the types of interference signals to eight.At the same time,the centralized management as well as programmed control and monitoring functions of ground test equipment can be realized by the use of virtual instrument and remote technology.Besides,the proposed test system has good human-computer interaction ability.The test results show that this test system can identify comprehensive types of interference signals,and has strong versatility,improving the efficiency of anti-interference test for DSSS system,which can be used in the anti-jamming performance test of spacecraft TT&C channels.
