| 摘 要： | 建立复杂脉冲包络探测信号的模糊函数是外辐射源探测系统仿真分析的重要内容．将复杂脉冲包络分成多个单脉冲，分别建立其自模糊函数和互模糊函数，再相互叠加，即可得到包络脉冲完整的模糊函数．本文以电视信号为例，建立并推导出了行周期内同步及黑白电平信号自模糊函数和互模糊函数的通用表达式，根据电视图像信号的脉冲性建立黑自全电视信号的模糊图，证明了建立复杂脉冲包络信号模糊函数的可靠性．

| Abstract: | The construction of the ambiguity function of complex pulse envelop is a key of simulation analysis of detection system based on opportunity transmitter. Dividing the complex pulse envelop into a number of single-pulses, building their auto-ambiguity and cross-ambiguity function respectively and then adding up them, the whole ambiguity function of the pulse envelop can be obtained. Take for example, television signal, the paper establishes auto-ambiguity and cross-ambiguity function of syne-pulse, black level and white level signal and derives their general expression. According to image signal pulse the ambiguity diagram of the whole black and white TV signal is obtained. It provides an efficiency approach for construction of the ambiguity func- tion of complex pulse envelop signal. |
