摘要
介绍了数字中频技术,指出其在雷达信号脉内调制特征分析方面的优势,并针对线性调频雷达信号,结合傅里叶变换提取雷达信号脉内调制规律和调制参数,软件分析结果证明本方法是有效的。
This paper introduces the digital intermediate frequency technology,pointes out that its advantages in pulse modulation feature analysis of radar signals,and aiming at the linear frequency modulation radar signal,combining with Fourier transforms,extracts the intra-pulse modulation law and modulation parameters of radar signals,the software analysis result proves that this method is effective.
