    摘要: A monopulse receiver, wherein a desired wide dynamic range is achieved for range gated monopulse sum and difference signals, is shown to incorporate: (a) a multiplexer for time-multiplexing such signals; (b) a first and a second receiver channel responsive to the time-multiplexed signals, each such channel having a dynamic range less than the desired wide dynamic range and greater than one-half the desired wide dynamic range, the gains in such channels being offset so that together such channels have the desired dynamic range; (c) a first and a second sampler and analog-to-digital converter, respectively, responsive to the signals out of the first and the second receiver channel, for producing digital words indicative of the amplitude of each component signal in the time-multiplexed signals; and (d) logic and control means for forming bytes from predetermined portions of each one of the digital words and for selecting the byte indicative of the amplitude of each component signal.
