Extract the Input Parameters of the RET Phase Function Using Jansson Deconvolution Method
The influence of vegetation on radio wave propagation has become an key aspect of the design of wireless communication links. In recent years the theory of Radiative Energy Transfer (RET) has been adopted as a reliable tool to predict propagation of radio wave through vegetation medium. The developed RET model requires 4 independent input parameters, which so far had to be extracted from measurement, which is termed phase function measurement. However one major factor limiting their accuracy of extracted parameters is the distortion caused by the receiving antenna radiation pattern. The measured pattern is the convolution product of the antenna pattern and the phase function. The measured pattern therefore needs to undergo an inverse process, i.e. deconvolution before any parameters can be derived from it This paper reports a deconvolution technique developed using Jansson method to remove the distortion at the receiver. This method is demonstrated on the signals measured in vegetation set up in an anechoic chamber.
