Includes bibliographical references (pages 25-26). "A simple I/Q demodulator which can be used to measure the amplitude, phase and instantaneous frequency of radar signals over a large bandwidth is investigated for electronic warfare applications. Imbalance errors and DC offsets are minimized by the techniques of component matching and calibration. A DFT technique is used to characterize the imbalances and DC offsets and improved matching characteristics on practical wideband demodulators are also given"--Abstract, page iii.
