signals processing optimization in interferometric SAR for accuracy IMPROVEMENT of height of the relief ESTIMATION

A.V. Yeremeyev

The problem of accuracy improvement of height of the relief estimation in interferometric synthetic aperture radar (SAR) is investigated. An optimal signal processing in primary radar information processing stage is proposed to solve the problem. The maximum likelihood approach is used for an optimal algorithm synthesis. As a model of the interferometric SAR, the vertical interferometer is considered. For the selected interferometer model, an optimal algorithm for height of the relief estimation is obtained.

Key words: interferometric SAR, height reconstruction, digital elevation model.
