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. The parametric encoders measure a corresponding plurality of frequencies and times of arrival of each of the first plurality of segment phase angles between corresponding segment signals having the same center frequency, of the first and second plurality of segment signals from the first and second channelizers, respectively.
