以压缩接收机工作机理线性调频傅氏变换为基础
对当前常用的长相乘短卷积压缩接收机模型特性进行了细致研究.参照模糊函数对雷达信号分析的方法
定义了压缩接收机输出函数
该函数描述了当与无损测频输出相比时
由雷达信号载频和实际脉冲展宽延迟线滤波器置空率引起的输出波形的变化.通过该函数可以对压缩接收机的频率分辨力、截获概率、到达时间等性能参数做出解析性分析.
Using the chirp Fourier transform which is the working mechanism of the compressive receiver
the most important construction long-multiplication
short-convolution is analyzed in edge frequency and non-complete intercept.By ambiguity function
the output waveform of this receiver is set up in this situation.The parameters of output waveform are discussed
which are the output pulse-width
output peak time delay
and output peak value loss.Then the performance of frequency detection by these parameters is deduced
including frequency coming time
frequency resolution and intercept probability.
