This paper describes the test method of active multi-beam antenna pattern by using high precision 3-axis antenna test turntable and the test procedure of antenna 3D pattern. And it presents the method of representing multi-beam antenna 3D pattern using 2D coordinate system and the method of obtaining multi-beam antenna 3D pattern by using MATLAB software to process test data .The test error of pattern is analyzed. Finally, The test results of active multi-beam antenna 3D pattern in a certain project show that this method is feasible.
