摘要
本文主要从波形设计的角度来研究MSK信号的定距、测距等探测特性.波形设计主要是通过研究信号的平均模糊函数、频谱特性等来分析该信号的性能.文中论述了MSK信号调制和相关解调的工作原理,分析了调制信号的模糊函数和回波信号相关峰解调的数学模型,给出了伪随机码长度和码元周期的选择原则和MSK信号的测距方法.最后,通过SystemView系统仿真,得出了MSK信号调制、解调的仿真波形以及不同延时回波的相关峰顶点分布图等.通过理论分析和仿真实现说明了MSK信号的良好定距、测距性能,同时也验证了波形设计方案的可行性.
The paper researched pseudo noise sequence MSK-modulation signal on target detection with respect to waveform design. Waveform design is to analyze waveform function from researching equally obscure function and spectrum function. This paper discussed the theory of modulation of MSK-modulation signal, provided the principle of pseudo noise sequence and cycle and the detection capability of MSK. Simulation analysis of MSK is also implemented by SystemView software. Results indicate the proposed method of waveform design is applicable.
