摘要
基于宽带模糊函数对子载波分别为单载频、线性调频、相位调制信号的多载波雷达信号特性进行了详细分析,讨论了子载波信号类型与其距离、速度轴特性以及邻道干扰影响的关系,研究了子载波为线性调频信号采用Dechirping处理时多载波合成的特点及减小峰值平均功率比的方法。
Muhicarrier radar signal is analyzed in detail in this paper. Based on wideband ambiguity function, the characteristics of multi-carrier signal with different modulation form are compared and discussed. Especially, influence of dechirping processing on the resolution synthesis is analyzed and a method to obtain low Peak-to-mean Power Ratio is proposed.
