Designing Optimal Bandwidth Synthesis Arrays for VLBI
نویسنده
چکیده
An approach toward choosing optimal sets of frequency channels for bandwidth synthesis in radio interferometry is presented and applied to 14-channel 2.2-/8.4-GHz (S-/X-band) very long baseline interferometry (VLBI) observations. It is shown that arrays with nonredundant autocorrelations in general have a higher ratio of the delay resolution function central maximum to the nearby side lobes than do arrays with partially or fully redundant channel spacings.

Multi-Frequency Synthesis of VLBI Images Using a Generalized Maximum Entropy Method
A new multi-frequency synthesis algorithm for reconstructing images from multi-frequency VLBI data is proposed. The algorithm is based on a generalized maximumentropy method, and makes it possible to derive an effective spectral correction for images over a broad frequency bandwidth, while simultaneously reconstructing the spectral-index distribution over the source. The results of numerical si...
متن کامل2 00 8 Towards millimeter VLBI
We discuss the present performance and the future perspectives of VLBI in the 3 mm to 0.85 mm observing bands (so called mm-VLBI). The availability of new telescopes for mm-VLBI and the recent technical development towards larger observing bandwidth and higher data-rates now allow to image with 3mm-VLBI hundreds of sources with high dynamic range. At 1.3 mm, pilot VLBI studies have proven detec...
متن کاملSynthesis of Antenna Arrays of Maximum Directivity for a Specified Sidelobe Level
Linear and planar antenna arrays are synthesized to have maximum directivity for a specified sidelobe level. The directivity is maximized subject to a given SLL. The beamwidth and the zeros of array factor are studied as well as the directivity. Maximum directivity-arrays are compared through some examples with super-directive, uniform, Dolph-Chebyshev and Riblet-Chebychev arrays to find a comp...
متن کاملNew Zealand involvement in Radio Astronomical VLBI Image Processing
With the establishment of the AUT University 12m radio telescope at Warkworth, New Zealand has now become a part of the international Very Long Baseline Interferometry (VLBI) community. A major product of VLBI observations are images in the radio domain of astronomical objects such as Active Galactic Nuclei (AGN). Using large geographical separations between radio antennas, very high angular re...
متن کاملDetermination of optimal bandwidth in upscaling process of reservoir data using kernel function bandwidth
Upscaling based on the bandwidth of the kernel function is a flexible approach to upscale the data because the cells will be coarse-based on variability. The intensity of the coarsening of cells in this method can be controlled with bandwidth. In a smooth variability region, a large number of cells will be merged, and vice versa, they will remain fine with severe variability. Bandwidth variatio...
