The invention relates to a super-high-dynamic spread spectrum signal fast-capturing method suitable for a reusable orbiter. The method comprises the steps that fast-capturing parameters of spread spectrum signals are calculated at first, then multiple channels of pseudo codes based on masks are generated, and fast capturing of the spread spectrum signals is achieved by conducting FFT analysis by turns at last. The specific steps are that a carrier frequency is divided into subsections, and signal capturing is conducted in each frequency subsection; multiple channels of parallel pseudo codes are generated in a mask mode, partial correlation operation is conducted on each channel of pseudo codes and input signals, and FFT conversion is conducted on multi-channel parallel correlation operation results by turns to save resources; after all frequency bands are traversed, precise values of carrier Doppler and pseudo code phases are obtained. The super-high-dynamic spread spectrum signal fast-capturing method suitable for the reusable orbiter effectively solves the spread spectrum signal fast-capturing problem of the reusable orbiter, and achieves fast capturing of the spread spectrum signals with the huge Doppler frequency offset and the dynamic range.
