低截获概率雷达复合信号设计技术

Design Technology of Complex Signals for LPI Radar

根据低截获概率 (Low Probability of Intercept)雷达信号应有的特点 ,从分析信号的相关函数和模糊函数入手 ,阐述了具有伪随机码相位调制和伪随机开关脉冲调制的复合信号设计与综合的原理 ,给出了这种信号可能的形式及每一种类型信号的可能应用场合 .

According to the characters of LPI radar signals, the general theory of complex signal designing and combination with pseudorandom code phase modulation and pseudorandom on off pulse modulation is proposed from analysing the correction and ambiguity function of signal.The possible forms and the application condition of each kind are presented.
