Y. Wang et Dg. Fang, NOVEL HIGH RANGE RESOLUTION APPROACH IN MICROWAVE IMAGING, IEE proceedings. Radar, sonar and navigation, 144(4), 1997, pp. 177-180
The authors propose a method of gaining range superresolution in a mic
rowave imaging system. After frequency domain deconvolution of echo to
the transmitted signal, the signal model is proved to be of the same
form as that of DOA estimation. Hence, as in the case of DOA estimatio
n, a nonlinear spectrum estimation algorithm can be applied to improve
range resolution. Numerical simulation and experiments have shown the
method to be cost-effective.
