Mirror point high dynamic suppressing correlator adaptive to spaceborne GNSS-R receiver

The invention discloses a mirror point high dynamic suppressing correlator adaptive to a spaceborne GNSS-R receiver. The correlator comprises a direct signal tracking module (1), a delay module (2), a mirror point high dynamic suppressing control module (3), a mirror point high dynamic suppressing processing module (4), a mirror point high dynamic suppressing infusing module (5), a carrier compensation module (6) and an interference processing module (7). The certain delay processing is performed on direct signals after carrier tracking firstly, the mirror reflection high dynamic suppressing is performed, interference processing is performed on reflection signals after carrier compensation, and the two-dimensional delay Doppler correlation power is acquired finally. The correlator is used for producing local copying carriers, local copying code generation is omitted, interference processing is performed on the direct signals and reflection signals after delay Doppler compensation processing, the Doppler frequency shift of one mirror reflection point in different sampling times can be acquired, the speckle noise of a mirror reflection region is suppressed, and the signal-noise ratio of the signals is increased.
