Use of FP-SPLIT Slits for Reaching High Signal-to-Noise with MAMA Detectors
نویسنده
چکیده
A pre-flight uncertainty for STIS was the extent to which the MAMA detectors would support high signal-to-noise observations given inherently low count rates, limitations on available flat fields, and the possibility of evolution in pixel-to-pixel response stability. This ISR reports on results from STIS/SMOV-7091 Pixel-to-pixel Response Stability in which spectra were acquired at high count levels through the FP-SPLIT slits with the express purpose of demonstrating the capability of reaching signal to noise of one hundred with the MAMA detectors. A S/N ratio of about 380 per resolution element was achieved for both FUVand NUV-MAMA data.

Adaptive Signal Detection in Auto-Regressive Interference with Gaussian Spectrum
A detector for the case of a radar target with known Doppler and unknown complex amplitude in complex Gaussian noise with unknown parameters has been derived. The detector assumes that the noise is an Auto-Regressive (AR) process with Gaussian autocorrelation function which is a suitable model for ground clutter in most scenarios involving airborne radars. The detector estimates the unknown...
متن کاملA Decision between Bayesian and Frequentist Upper Limit in Analyzing Continuous Gravitational Waves
Given the sensitivity of current ground-based Gravitational Wave (GW) detectors, any continuous-wave signal we can realistically expect will be at a level or below the background noise. Hence, any data analysis of detector data will need to rely on statistical techniques to separate the signal from the noise. While with the current sensitivity of our detectors we do not expect to detect any tru...
متن کاملThe Flat Fielding and Achievable Signal-to-Noise of the MAMA Detectors
The Space Telescope Imaging Spectrograph (STIS) was designed to achieve a signal-to-noise of at least 100:1 per resolution element. MAMA observations during Servicing Mission Orbital Verification (SMOV) confirm that this specification can be met. From analysis of a single spectrum of GD153, with counting statistics of ∼ 165 a S/N of ∼ 125 is achieved per spectral resolution element in the FUV o...
متن کاملDesign of robust carrier tracking systems in high dynamic and high noise conditions, with emphasis on neuro-fuzzy controller
The robust carrier tracking is defined as the ability of a receiver to determine the phase and frequency of the input carrier signal in unusual conditions such as signal loss, input signal fading, high receiver dynamic, or other destructive effects of propagation. An implementation of tight tracking can be understood in terms of adopting a very narrow loop bandwidth that contradict with the req...

The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...
