Calibration: Hardware Schemes
In this section, hardware solutions to the problem of calibrating the MMA amplitude and phase are described. Both solutions use the blocked area in the center of the subreflector as the source of radiation from either a two-temperature load or a cohere nt signal source. A simple mirror mechanism is used to select between the two systems. The coherent source may be made phase stable through a ro...
متن کاملRegion-Enhanced Passive Radar Imaging
We adapt and apply a recently-developed region-enhanced synthetic aperture radar (SAR) image reconstruction technique to the problem of passive radar imaging. One goal in passive radar imaging is to form images of aircraft using signals transmitted by commercial radio and television stations that are reflected from the objects of interest. This involves reconstructing an image from sparse sampl...
متن کاملNew adaptive interpolation schemes for efficient meshbased motion estimation
Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...
متن کاملPassive Replication Schemes in Aqua
Building large-scale distributed object-oriented systems that provide multidimensional Quality of Service (QoS) in terms of fault tolerance, scalability, and performance is challenging. In order to meet this challenge, we need an architecture that can ensure that applications’ requirements can be met while providing reusable technologies and software solutions. This paper describes techniques, ...
