Abstract:
A missile-based guidance system, comprising:an analog guidance signal detector; an analog-to-digital converter for converting analog guidance signals from said analog guidance signal detector to digital guidance signals and outputting said digital guidance signals on first and second channels; and a digital predetection signal processor coupled to said first and second channels, including a main channel processor and a dual path processor for performing predetection calculations, said main channel processor and said dual path processor each including at least two digital filters each for filtering said digital guidance signals before said signals are input into said main channel processor and said dual path processor; said digital filters each being programmable to digitally filter said digital guidance signals to thereby minimize output signal error; said main channel processor and said dual path processor each utilizing common input guidance signals for predetection calculations.
