Microlocal Analysis of Multistatic Radar Imaging
2024 International Radar Conference (RADAR)We consider the synthetic aperture radar experiment in which waves, simultaneously emitted from a pair of stationary emitters, are scattered by objects and measured by a receiver that makes multiple passes over the scattering region.

[For the entire collection see Zbl 0777.00009.] Cet ouvrage est composé de deux parties bien distinctes: l'une, écrite par Yu. V. Egorov, portant sur la théorie microlocale, avec divers résultats entrant dans le sujet; l'autre écrite par V. Ya. Ivrii, concernant surtout la théorie des équations hyperboliques linéaires.

INTRODUCTION TO MICROLOCAL ANALYSIS
1986[This article has already been published in Monographie de l'Enseignement Mathématique, No.32 (Université de Genève, 1986; Zbl 0592.58051).] The author gives a survey of microlocal analysis from the hyperfunction point of view. The following topics are treated: systems of differential equations, microdifferential operators, symplectic structure of the ...

Selected lectures in Microlocal Analysis
2009This paper surveys classical results on microlocal analysis. It also includes more recent theorems on propagation at a non-microcharacteristic boundary: these are a boundary microlocal version of Holmgren’s uniqueness Theorem.

Morera theorems via microlocal analysis
Journal of Geometric Analysis, 1996More general Morera theorems state that, if \(y(c)= \int_c fdz=0\) for certain subclasses of closed curves in a region, then \(f\) is holomorphic in that region. The present paper shows Morera theorems for circles passing through the origin, for circles of arbitrary radius and arbitrary center, and for translates of a fixed closed convex curve.

The prototype of the equations described in the introduction is the simple semilinear wave equation $$U = \{ \partial_t^2 - \sum\limits_{{i = 1}}^n {\partial_{{{x_j}}}^2} \} U = f\left( {t,X,U} \right). $$ (1.1) with f an arbitrary smooth function.

Resonances and microlocal analysis
International Journal of Quantum Chemistry, 1987AbstractIn this paper we outline briefly how microlocal analysis can be applied to give a general approach to the mathematical theory of resonances in the semiclassical limit. We also describe recent results about the asymptotic behavior of resonances generated by closed trajectories and stationary points in the classical flow.

Introduction to Microlocal Analysis
2019In this chapter we give a survey of the theory of h-pseudodifferential operators (in Section 1.1), h-Fourier integral operators (in Section 1.2), the notion of wave front sets and related topics (in Section 1.3). Proofs are mostly sketchy since all the results of this chapter are trivial consequences of the results proven in L. Hormander’s monograph [1]
