A Circular Aperture Array Configuration with a Small Antenna Radius
In this paper, small sized array configurations with small number of element are investigated. As the antenna size, the diameter less than 3λo is assumed. The investigated configurations are a non-uniform arrangement, Triangular arrangement and uniform arrangement. The gain characteristics of these configurations is calculated using the method of moment and compared them. As a result, it is fou...
متن کاملAn Aperture-Coupled Linear Microstrip Leaky-Wave Antenna Array with Two-Dimensional Dual-Beam Scanning Capability
This paper describes an -band 4 1 aperture-coupled series-fed electronically steerable microstrip leaky-wave antenna (LWA) array design, which has dual-beam radiation pattern and two-dimensional (2-D) beam-scanning capability. The LWA array is operated in the first higher order mode and excited by center-fed aperture coupled for dual-beam operation. The varactor-tuned phase shifters are placed ...
متن کاملLaser-Interferometric Broadband Seismometer for Epicenter Location Estimation
In this paper, we suggest a seismic signal measurement system that uses a laser interferometer. The heterodyne laser interferometer is used as a seismometer due to its high accuracy and robustness. Seismic data measured by the laser interferometer is used to analyze crucial earthquake characteristics. To measure P-S time more precisely, the short time Fourier transform and instantaneous frequen...
متن کاملLarge Aperture Seismic Array Capabilities
This report presents the results of a study of the effectiveness of the experimental Large Aperture Seismic Array in Montana. An attempt has been made, where possible, to draw conclusions from the study of this one station about the performance that might be expected from a worldwide net of several of them. The report discusses the reliability and continuity of observations obtainable from a LA...
متن کاملMatched Field Processing Based on Least Squares with a Small Aperture Hydrophone Array
The receiver hydrophone array is the signal front-end and plays an important role in matched field processing, which usually covers the whole water column from the sea surface to the bottom. Such a large aperture array is very difficult to realize. To solve this problem, an approach called matched field processing based on least squares with a small aperture hydrophone array is proposed, which ...
