Hybrid D Sigma-delta Stap Algorithm in Non- Homogeneous Clutter
The need to deal with non-homogeneous clutter has driven much of the recent research in space-time adaptive processing (STAP). This paper presents an extension of the low-complexity, sigma-delta (ΣΔ) algorithm incorporating the direct data domain (D) processing. The new algorithm is practical and improves target detection in non-homogeneous clutter environments. The algorithm employs a hybrid a...
متن کاملTwisting gauged non-linear sigma-models
We consider gauged sigma-models from a Riemann surface into a Kähler and hamiltonian G-manifold X. The supersymmetric N = 2 theory can always be twisted to produce a gauged A-model. This model localizes to the moduli space of solutions of the vortex equations and computes the Hamiltonian Gromov-Witten invariants. When the target is equivariantly Calabi-Yau, i.e. when its first G-equivariant Che...
متن کاملDiscrete Time Homogeneous and non-Homogeneous semi-Markov Reliability Models.∗
In this paper, we extend to our knowledge, for the first case, some reliability results obtained using homogeneous semi-Markov processes to the case of non-homogenous semi-Markov modelisation. Moreover, we apply some of our preceding results to give the numerical solutions and so the possibility to treat real life problems for which non-homogeneity in time is important.
متن کاملForecasting with non-homogeneous hidden Markov models
We present a Bayesian forecasting methodology of discrete-time finite statespace hidden Markov models with non-constant transition matrix that depends on a set of exogenous covariates. We describe an MCMC reversible jump algorithm for predictive inference, allowing for model uncertainty regarding the set of covariates that affect the transition matrix. We apply our models to interest rates and ...
متن کاملDualised σ-models at the two-loop order
We adress ourselves the question of the quantum equivalence of non abelian dualised σ-models on the simple example of the T-dualised SU(2)σ-model. This theory is classically canonically equivalent to the standard chiral SU(2)σ-model. It is known that the equivalence also holds at the first order in perturbations with the same β functions. However, this model has been claimed to be non-renormali...
