The utility model has the advantages that compared with prior art, the present invention its remarkable advantage is: the present invention provides a kind of based on radio-frequency fingerprint
Identification pseudo gps signal method, can be applied to identify pseudo gps signal, guarantee gained signal it is true and reliable.By being defended to puppet
The capture of star and real satellite transmitting signal, to signal processing and calculates Doppler frequency shift, and by the size of Doppler frequency shift
To identify to signal.The present invention identifies actual signal and false signal as radio-frequency fingerprint using Doppler frequency shift, calculates
Complexity is small, and has preferable distinguishing ability.
Detailed description of the invention
Fig. 1 is the hardware device connection figure that the embodiment of the present invention is applicable in；
Fig. 2 is the flow diagram of the embodiment of the present invention；
Fig. 3 is pseudo gps signal Doppler frequency shift change curve；
Fig. 4 is true GPS signal Doppler frequency shift change curve.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
Present embodiments provide a kind of identification pseudo gps signal method based on radio-frequency fingerprint, based on hardware device such as
Shown in Fig. 1, sending device is one piece of HackRF Software Radio platform, emits pseudo gps signal in L1 frequency range, false signal is by soft
Part defines GPS signal emulator gps-sdr-sim generation, which comes from GitHub, and reception device is on same PC
HackRF platform.The transmitting-receiving of false signal is completed by same PC terminal, and the radio-frequency fingerprint of false signal is extracted through MATLAB reality
It is existing.Known to theory analysis: true GPS signal often has biggish Doppler shift due to the relative motion of satellite and receiver
Variation, and pseudo gps signal is since flat pad is static, therefore the shake very little of its Doppler shift.Therefore signal is how general
Strangling after frequency deviation is handled can be used as the radio-frequency fingerprint for distinguishing false signal and actual signal.
As shown in Fig. 2, the identification pseudo gps signal method based on radio-frequency fingerprint of the present embodiment mainly includes two parts,
One be radio-frequency fingerprint in false signal extraction, be embodied on following step (1)-(4)；The second part is exactly to penetrate in false signal
The identification of frequency fingerprint is embodied on step (5), specifically:
(1) sending device sends signal by multipath channel, sends signal derived from GitHub downloading in the present embodiment
GPS signal simulative generator code；
(2) receiving device receives signal and is pre-processed, and obtains echo signal, wherein pretreatment includes down coversion, phase
One of compensation, energy normalized, the unqualified signal of discarding etc. are several；Using energy normalized in the present embodiment
