摘要 根据雷达辐射源信号的不同特性,提取其非线性相位方差、瞬时频率统计直方图、瞬时频率方差和相像系数等特征量,对单载频、线性调频、非线性调频、频率编码和相位编码等常用雷达辐射源信号调制形式进行多参数联合判决。仿真结果表明,该算法在低信噪比下,仍能够自动准确地识别雷达信号脉内特征。 The automatic radar impulse character recognizable algorithm is presented in this paper. Its variance of nonlinear phase, statistical histograms of IF (Instant Frequency) , variance of IF and resemblance coefficient are extracted based on different characteristics of radar illuminator signals, which then are combined together to classify the common modulation, such as CW signal, LFM signal, NLFM signal, FSK signal and PSK signal. Simulation result shows it is effective even with a low signal-to-noise ratio.
