中文摘要：
对非合作双基地雷达中直达波参考信号受到噪声干扰和多径干扰影响的问题进行了理论分析和数学建模。在此基础上,仿真分析了这两种干扰对直达波信号波形的影响。针对这一问题,提出了一种直达波信号重构方法,并给出了详细的数学推导。仿真结果表明,该方法重构出的直达波信号波形失真度很低,能有效地去除非合作双基地雷达直达波参考信号中的噪声干扰和多径干扰。
英文摘要：
The problem that the direct-path reference signal is affected by noise and multi-path interference signals is analyzed,and then the simulation model on the problem is established.On the basis of the analysis and the simulation model,the waveform of the direct-path pulse signal under noise and multi-path interference signals is simulated.To mitigate this problem,a new method for direct-path reference signal reconstruction is proposed,and a full mathematical derivation is provided in detail.The simulation results show that the waveform degree of distortion of the direct-path reference signal reconstructed by this new method is very low,and the noise and multi-path interference signals can be removed from the direct-path reference signal effectively.
