Abstract
Modern high-performance radar systems’ data is often rendered to distinguish between positive and negative frequencies necessitating complex data values, with real and imaginary constituents typically termed In-phase (I) and Quadrature (Q) elements respectively. Processing this data generally assumes well-balanced I/Q data, which may often be problematic due to non-ideal component and circuit behavior. We offer a number of techniques to mitigate the effects of I/Q imbalance.
