Ever since the FCC approved the use of UWB devices in commercial and federal bands, various agencies whose operations and/or products rely on the integrity of signals within certain "restricted" radio frequency bands have voiced concerns over the pot

A method for digital determination of a single frequency from a sine wave sampled at less than the Nyquist rate is discussed. The method makes use of phase shift information to eliminate the aliasing ambiguity. Multiple sampled data are required to e

Digital wideband receivers are essential elements used in electronic warfare applications. Instantaneous Frequency Measurement (IFM) receivers are suitable for use in EW systems due to the ultra-wideband instantaneous radio- frequency (RF) bandwidth,

The results of a study of the sensitivity of digital electronic warfare (EW) receivers are reported. It is demonstrated with actual digitized data that the sensitivity of a digital receiver can be improved if enough signal processing is applied. The

The effects of amplitude and phase imbalances between the in-phase and quadrature channels of a digital radio frequency (RF) receiver on a phase analysis processing technique are studied. Particular attention is given to the effect that these errors
