Radio Polarimetry of Tycho's SNR [PDF]
Symposium - International Astronomical Union, 1990 The remnant of Tycho's supernova of 1572 has been polarimetrically imaged using the 4 configurations of the VLA at wavelengths of 22 and 6 cm. A few data were also obtained at wavelengths of 21, 19, and 18 cm in the B configuration to check for any ambiguities in the Faraday rotation measurements and to look for deviations from the λ2 dependence of the

SNR Comparisons of Beamforming Strategies [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2007 This paper defines the echo signal-to-noise ratio (eSNR) for pulse-echo systems that adapts to the effects of shift-varying impulse responses, spatiotemporal coding, and various beamformers. Measurement techniques using point targets or random scattering media can be interrelated for a broad range of experimental conditions through the eSNR.
