Phase imbalance compensation in SAR/ISAR quadrature demodulation

2009 2nd Asian-Pacific Conference on Synthetic Aperture Radar, 2009
I/Q channel imbalance in quadrature demodulation is one of the major concerns in the design of synthetic aperture radar (SAR) and inverse SAR (ISAR) receivers. The amplitude and phase mismatches result in the additional mirror signal, which acts as a correlated interference superimposed on the desired signal and, hence, degrades the whole system's ...

Evidence for charge imbalance waves in phase-slip centers

Physica B+C, 1981
Abstract We have examined the I-V characteristics of superconducting phase-slip centers (PSCs) located in the middle of narrow In channels. Features in dV/dI can be associated with resonances in charge imbalance waves driven by the PSC, as suggested by the model of Kadin, Smith and Skocpol.

A gain/phase imbalance minimization technique for LINC transmitter

2001 IEEE MTT-S International Microwave Sympsoium Digest (Cat. No.01CH37157), 2002
A simple calibration scheme for correction of the path imbalance in a LINC transmitter has been demonstrated. In this algorithm a baseband DSP evaluates the gain and phase imbalance with a set of calibration signals through a feedback loop. Compensation of path imbalance is accomplished within the DSP by introducing a pre-distortion term.

The Identification of Amplitude and Phase in Imbalance Mass of Grinding Wheel

Key Engineering Materials, 2011
Vibration signal produced by imbalance of grinding wheel is a periodic signal that has a same frequency with rotational speed. To identify the signal accurately is premise of balance for grinding wheel. This paper introduces the composition and basic concept of vibration signal in grinding wheel and further studies how to identify process and calculate
