| Abstract: |
| For the case of GPS satellite reception system does not work in the presence of broadband interference，we research the adaptive anti-jamming technology based on the array antenna.A constrained minimum variance algorithm is given to suppress the interference.The Algorithm utilizes the difference of angles between signal and interference to filter interference,so that the beam can point to the satellite signals，protect the useful signals and greatest suppress the interference.The hardware implementation is given based on the algorithm.Finally,we simulated the algorithm and analyzed it in detail,verified the effectiveness of the algorithm. |
