Analysis and characterization of a monobit receiver for electronic warfare

Detection of simultaneous signals and real-time operation are basic characteristics in broadband electronic warfare (EW) receivers. A digital channelized monobit receiver represents an attempt to achieve both features at the expense of low instantaneous dynamic range. This paper presents a detailed theoretical and experimental analysis, and characterization of the performance of this promising receiver composed of a monobit analog-to-digital converter (ADC) and a filter bank based on a monobit implementation of the discrete Fourier transform (DFT).
