针对已有算法应用的局限性,以线性调频,二相编码,频率编码和正弦等典型射频信号为例,提出了一种基于二维离散傅立叶变换的射频信号调制类型识别新算法,重点阐述了信号自相关变换过程和运算量分析,计算机仿真结果验证了本算法确实有效.

Taking LFM signal,biphase coded signal,FSK,single frequency of the RF signal as examples,this paper proposes an algorithm to achieve Modulation pattern recognition based on Two-Dimension Dispersed Fourier Transform aim at lacalization of existed algorithms.,we spend more effort on self-correlation matrix and analysing operation scale, Simulations is carried out to demonstrate the effectiveness of the proposed algorithm.
