I use the simplest because it doesn't require any data other then dual-baseline INSAR. The more advanced models require POLSAR data because they consider orientation in the vegetation medium. Very littel is explained in this paper about how the numerical inversion is implemented. I learned through personal discussions with Robert Treuhaft that he used basic least-squares normal equations. His reference was [Hamilton]. It is the most basic approach to nonlinear estimation that you can use.[bibtex-entry]

It refers to LG90 and subsequent JPL-authored papers refer to this one. It is not very easy to read though.[bibtex-entry]

It compares 4 major adaptive estimation methods: Bayesian, Maximum likelihood, correlation-based, and covariance matching. It also has a great bibliography where it lists several references dedicated to each method. This is a ``short paper'' so no volume or number in the citation.[bibtex-entry]
