Abstract
Application of ultra-wideband signals with linear frequency modulation in the behind barriering radiolocation.
Incoming article date: 23.03.2016Discusses the use of complicated UWB signals in supergrades and subsurface radiolocation. The aim of this work is to analyze the possibility of complex UWB signals using a simpler aproximarse signals, which greatly simplifies the task of finding the basic parameters of the echo signal. As a model of the complex signal of the selected signal with linear frequency modulation. Designed the error of approximation of ultra-wideband LFM echo signal of the echo signal with a rectangular spectrum with different environment settings and the coefficients of the high bandwidth. Based on these data it is concluded that at high modulation indices it is possible to replace the analytical calculations of complex expressions for the spectrum of the chirp signal by a simple ratio aproximarse spectrum.
