نویسندگان
چکیده
We present a method to characterize the noise in ground-based gravitational-wave observatories such as Laser Gravitational-Wave Observatory (LIGO). This uses linear regression algorithms least absolute shrinkage and selection operator identify sources analyzes detector output vs witness sensors quantify coupling of noise. Our can be implemented with currently available resources at LIGO, which avoids extra coding or direct experimentation LIGO sites. two examples validate estimate elevated ground motion frequencies below 10 Hz output.

Seismic Isolation for Advanced LIGO
The baseline design concept for a seismic isolation component of the proposed “Advanced LIGO” detector upgrade has been developed with proofof-principle experiments and with computer models. It consists of a two-stage in-vacuum active isolation platform that is supported by an external hydraulic actuation stage. Construction is underway for prototype testing of a full-scale preliminary design.
متن کاملUsing a novel method for random noise reduction of seismic records
Random or incoherent noise is an important type of seismic noise, which can seriously affect the quality of the data. Therefore, decreasing the level of this category of noises is necessary for increasing the signal-to-noise ratio (SNR) of seismic records. Random noises and other events overlap each other in time domain, which makes it difficult to attenuate them from seismic records. In this r...
متن کاملLow-frequency seismic deghosting
We evaluated a solution to seismic deghosting that deghosts the low-frequency components of the seismic pressure data. In an approximation that neglected the dependence on wavenumbers, the low-frequency deghosted pressure field was computed trace-by-trace as the sum of the pressure field and its scaled temporally integrated and temporally differentiated fields. We gave simple numerical examples...
متن کاملApplication of Single-Frequency Time-Space Filtering Technique for Seismic Ground Roll and Random Noise Attenuation
Time-frequency filtering is an acceptable technique for attenuating noise in 2-D (time-space) and 3-D (time-space-space) reflection seismic data. The common approach for this purpose is transforming each seismic signal from 1-D time domain to a 2-D time-frequency domain and then denoising the signal by a designed filter and finally transforming back the filtered signal to original time domain. ...
متن کاملA Concurrent Dual-Band Low Noise Amplifier for GNSS Receivers
In this paper, a new design of concurrent dual-band Low Noise Amplifier (LNA) for multi-band single-channel Global Navigation Satellite System (GNSS) receivers is proposed. This new structure is able to operate concurrently at frequency of 1.2 and 1.57 GHz. Parallel and series resonance parts are employed in the input matching in order to achieve concurrent performance. With respect to used pse...
