摘要: 针对跟踪及数据中继卫星系统(TDRSS)S波段扩频链路的特点,依据最佳干扰理论,提出了基于信号波形与干扰码元波形的互相关函数的瞄准式干扰的干扰方程,并证明均值意义下的干扰方程就是衡量最佳干扰波形的条件.蒙特卡罗仿真结果表明,对于方波、半正弦和升余弦3种瞄准式干扰波形,方波干扰方程的均值最大,即方波为最佳干扰波形.

Abstract: A new analytic technique for optimal jamming waveforms is presented. Based on the performance of TDRSS S-band spread spectrum links, according to the theory of optimal jamming, the spot jamming equation is presented based on the correlation function between signal waveforms and jamming codes waveforms. Then it is proved that the jamming equation in the sense of the equal value is the optimal jamming waveform condition. Finally, the Monte-carlo simulation results illustrate that the optimal jamming waveform is a square waveform, because its equal value of jamming equation is larger.

Key words: TDRSS, spot jamming, simulation
