临近空间双基地雷达信号衰减问题研究

Research of signal attenuation problem in near-space bistatic radar

研究一种基于临近空间平台的新型双基地雷达在衰减方面的性能,讨论了该雷达在探测目标过程中的衰减问题。利用D.E.Kerr给出的绕射衰减因子求解方法,计算了在不同基线及波长情况下的绕射衰减因子及雷达探测距离,总结绕射衰减因子及其对探测距离所造成的影响的一些变化特点;分析了该雷达在中层大气环境中的大气衰减情况。

This paper discusses the radar＇s signal attenuation problem, which belongs to a new kind of bistatic radar based on the near-space. There is a kind of means to figure out diffraction attenuation of D. E. Kerr, which can use this to figure out diffraction attenuation and detect distance in different baseline and wavelength. This paper summarizes some changing orderliness and analyses the atmosphere attenuation in middle-level.
