Combined Vision System (CVS) that provides pilots a combination display with synthetic image and enhanced real vision requires critical image alignment. However, airborne navigation sensors are not accurate enough to support ideal alignment of synthetic and real image in CVS naturally. In this paper we investigate the effects of aircraft position and attitude errors on the projection accuracy of synthetic...
In this paper, we aim at studying the laws of heat, moisture and air transfer in the respirable walls. We developed a coupled unstable equation system of the heat, air and moisture transfer in the respirable walls with the third boundary condition. Because equal equation systems are a series of non-linearity equations, which include differential items, finite difference is adopted to solve the equation...
In this paper, we propose a least-squares-based method for multitemporal synthetic aperture radar interferometry that allows one to estimate deformations without the need of phase unwrapping. The method utilizes a series of multimaster wrapped differential interferograms with short baselines and focuses on arcs at which there are no phase ambiguities. An outlier detector is used to identify and remove...
VHF (Very High Frequency) navigation system is an important part of the modern airplane, supplying the real-time navigation parameters. In the case of laboratory, in order to shorten the developing time and save the resources, we always use system model replacing the real system to accomplish the assignment. This paper, aiming at VHF navigation, will establish the mathematic model based on Software-Defined...
