Joint inversion method of dielectric constant and concealed target parameters of homogeneous background media

The invention provides a joint inversion method of dielectric constant and concealed target parameters of homogeneous background media, which is realized by the following ways: firstly setting an estimation interval of a dielectric constant, then computing each estimation value in the interval to generate dictionary matrixes, then arranging the dictionary matrixes in rows to generate a joint dictionary matrix, carrying out optimization solution by utilizing imaging algorithm based on compressed sensing on the basis of the joint dictionary matrix to obtain a joint target matrix, then segmenting and extracting the joint target matrix and simultaneously obtaining the dielectric constant and the imaging results of the detection regions of the background media, thus improving the real-time detecting and imaging capabilities of the ground penetrating radars to a greater extent.
