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.

Abstract

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.
