摘要:

研究了直扩/跳频测控信号伪码跟踪的抗干扰性能，通过加权处理使其归结为分析干扰条件下直扩信号伪码跟踪性能。采用鉴相曲线的过零点偏移表示干扰对跟踪的影响，推导了伪码跟踪的最大干扰误差表达式。以单音信号作为输入干扰，对最大干扰误差进行了理论分析，得出了音频干扰对伪码跟踪的影响规律。仿真结果表明，理论分析与仿真结果吻合较好，验证了理论分析的正确性。

Abstract:

Direct Sequence/Frequency Hopping Telemetry, Tracking & Command (DS/FH TT&C) signals code tracking anti-jamming performance is studied, which is trans lated into the DS signals code tracking performance under jamming by weighted av erage method. Using the zero value point shift of the phase discriminator curves to evaluate the jamming impact on the code tracking performance, jamming maximu m error (JME) expression of code tracking is derived. The JME under tone jamming is deduced, and the rule of impact of tone jamming on code tracking is acquired . Simulation results show that theoretical analysis is in good agreement with si mulation results, which validates the JME expression.

Key words: DS/FH hybrid spread spectrum TT&C signals code tracking tone jamming jamming max imum error
