An antenna array receiving signal model is set up in order to compare and analyze the anti-jamming comprehensive performance of the two kinds of algorithm including Power Inversion(PI) algorithm and Minimum Variance Distortionless Response(MVDR), which are based on Linear Constrained Minimum Variance(LCMV) criterion. Based on the module, theoretical analysis of the principle and characteristics of PI and MVDR are carried out. The comparison and analysis of the influence between spread spectrum signal capture and carrier phase are implemented. Besides, Matlab is adopted to validate the analysis results and perform future analysis. The final conclusion is that MVDR is better than PI. This work shows important guiding significance for engineering practice in the field of satellite navigation anti-jamming.
