EVLA Memo 163 Recirculation in WIDAR with phase serialization
نویسنده
چکیده
A fundamental aspect of the WIDAR correlator is that the sampled astronomical datastream from each antenna is accompanied by a model phase stream. This model phase accounts for, amongst other things, natural fringe rate and the fshift frequencies that are used to frequency shift the data stream from each antenna. The phase models of the two antennas of a baseline are used for fringe stopping and fshift removal in the lag correlator cells that make up WIDAR.

EVLA Memo 160 More WIDAR spectral dynamic range tests
This is a continuation of investigation of the spectral dynamic range achievable with the WIDAR correlator. Previous investigations (EVLA Memo 148) were limited by the so-called “splatter” phenomena, which is now understood and avoidable (EVLA Memo 157). This investigation is also stimulated by a desire to evaluate the “correlator chip beat artifact” seen in simulations (NRC-EVLA Memo 32) and t...
متن کاملEVLA Memo 148 WIDAR anti-aliasing and spectral dynamic range test
WIDAR, the correlator being commissioned as part of the EVLA upgrade, allows observing with multiple simultaneous subbands. Intrinsically WIDAR produces many channels within each subband. WIDAR aims to be a system with high spectral purity. In particular, WIDAR aims to produce low non-ideal in-band response of a spectral feature, low aliasing of a spectral feature from one subband to another, a...
متن کاملEVLA Memo 64 Wide-Field Imaging with the EVLA: WIDAR Correlator Modes and Output Data Rates
Of all the anticipated imaging problems to be undertaken by the EVLA, the most demanding, both in terms of data rate, data storage and post-processing, will likely be that of wide-band, wide-field imaging imaging the entire antenna primary beam with the full bandwidth. In this memo, I summarize the correlator requirements for various observing scenarios with the EVLA: distortion-free imaging of...
متن کاملWIDAR Correlator Sensitivity Losses
This short memo presents the results of simulation tests that empirically quantify quantizer sensitivity losses in the WIDAR correlator for the EVLA. These results demonstrate that 3-bit/8-level quantization suffers a ~3.7% sensitivity loss and that 4-bit/15-level quantization suffers ~1.3% sensitivity loss. The results will also show that a WIDAR correlator with 3-bit initial quantization and ...
متن کاملSimulation Tests to Quantify the Spectral Dynamic Range and Narrowband Interference Robustness of the WIDAR Correlator for the EVLA
In the first memo of this series [1], a number of simulations were performed with the primary goal of quantifying the performance of the proposed WIDAR correlator compared to an ideal correlator operating at the full bandwidth. These simulations demonstrated that the WIDAR correlator yields satisfactory results. It was also stated and demonstrated that the WIDAR correlator could increase the sp...
