On Evolutionary Inverse Problems for Parabolic Equations
. Such inverse problems arise in the study ofheat and mass transfer, diffusion, tracer dispersion, etc.Among the works concerning such problems, we notethose by Yu.E. Anikonov, Yu.Ya. Belov, M. Ivanchov,and some other authors (see the bibliography in [1–5]).However, previous studies considered linear or the sim-plest quasilinear cases, the governing equations werefrequently one-dimensional, and their coefﬁcients gen-erally did not depend on x ’’ .rxt(),∂u∂t------ – L
A MMW radiometer is widely used in remote sensing and guidance. In order to obtain the real brightness temperature distribution of the target, we need to solve the first kind of ill Fredholm integral equation of radiometric antenna temperature. The paper presents a kind of inversion method for modifying antenna pattern and the approach of error compensation. Compared with the theoretical calculation model of 3mm smooth water surface, the results show this algorithm has a higher accuracy for the measurement application.
