探地雷达最优工作信号与脉冲波形畸变的整形技术

Optimum Signals for Subsurface interface Radars and Rectifying Technique for Distorted Pulses

利用信号检测理论，在雷达接收天线端信号的信噪比最大时，推出浅层地下目标探测雷达的工作信号形式是基带脉冲。该脉冲波是媒质参数、目标特性和目标埋深的函数。脉冲波在有耗媒质中传播时，既要引起幅度的衰减又要产生波形失真。通过分析波形失真的原因，提出了一种对失真波形进行整形的方法。

From signal detecting theory,the optimum transmitted signals for subsurface interface radars arededuced,which are baseband pulses when the Signal/Noise in receiving antenna is maximum.The shape of the optimum pulses is shown to be a function of the medium parameters and the depth of the buried targat.I3oth the amplitude and the shape of the pubs are changed when propagating through a lossy medium.A rectifying technique for the distorted pulse is put forward.
