Phase unwrapping is one of important task in synthesizes aperture radar (SAR) interferometric measurement data processing procedure. Accuracy of it will directly affects precision of the interferometric measurement result. Through the experimental study, this paper analyzes principle and the characteristic of two kind of main current phases unwrapping algorithm, then conbines respective merit a...

We present a stochastic path integral formalism for continuous quantum measurement that enables the analysis of rare events using action methods. By doubling the quantum state space to a canonical phase space, we can write the joint probability density function of measurement outcomes and quantum state trajectories as a phase space path integral. Extremizing this action produces the most likely...

The paper presents a new approach to the radiation pattern reconstruction from near-field amplitude only measurement over a two planar scanning surfaces. This new method for antenna pattern reconstruction is based on the global optimization PSO (Particle Swarm Optimization). The paper presents appropriate phaseless measurement requirements and phase retrieval algorithm together with a brief des...
