The Study Of The Mode Of GPS's Interference

This thesis focuses on the schemes and efects of interference GPS's C/A-coded receivers using both CW and Gold code-modulated BPSK signals,and the Gold code is incoherent to that adopted by GPS.By integrating GPS downlink and jammer into one model, simulating with Monte Carlo method and programming in MATLAB language, the computability is achieved and then various interference results, in terms of error rate, are obtained as follows:The efect with Gold code is much beter than with CW;Increasing the jammer's height appears very efective;The quantitativere lations,with the jammer's power and the distance to GPS receiver,are probed respectively.Based on the computing and analysis, some kind of "airborne distributed/multiplatformed jammer system" is highly recommended for neutralizing possible GPS-imbedded intruders.
