Abstract: An apparatus for detecting an intercept signal having spread spectrum modulation, having a first antenna, a second antenna, a first channelizer, a second channelizer, parametric encoders, a spread hopper processor and a nonspread hopper processor. The first antenna outputs a first sample of the intercept signal. The second antenna outputs a second sample of the intercept signal. The first channelizer channelizes the spectrum of the first sample of the intercept signal into a first plurality of spectrum segments, with each spectrum segment having a corresponding segment signal, respectively. The second channelizer channelizes the spectrum of the second sample of the intercept signal into a second plurality of spectrum segments having the same center frequencies and bandwidths as the first plurality of spectrum segments. Each spectrum segment of the second plurality of spectrum segments has a corresponding segment signal, respectively.
