Application of Vector Accumulation Algorithm to Correlation Interferometer DF

This paper uses the method of vector accumulation to improve the performance of direction finding(DF)of correlation interferometer,presents the algorithm flow of vector accumulation based on correlation interferometer DF model,according to the statistical characteristic of narrowband Gaussian white noise and the algorithm flow of vector accumulation,theoretically analyzes the theory to improve signal-to-noise ratio(SNR)by vector accumulation algorithm.Both the simulation and test prove the validity of the method.Finally some advices for engineering implementation are proposed.
