摘要：
An adjacent pattern power ratio algorithm is proposed for DoA estimation with a switched beam antenna. For a single source signal, the received signal powers are measured while the antenna switches over a set of directive beam patterns. The pattern that exhibits the maximum received signal power is chosen. Then, the ratio between the pattern adjacent to the chose pattern and the chose pattern, is used to find the DoA by using a lookup table or by performing a linear regression approximation. Compared with conventional DoA estimators, the proposed algorithm allows DoA estimation with low computational cost, without sacrificing the estimation precision.
