[0063] The specific implementation steps are:
[0064] (1) Select the arrangement method of the reference antenna array elements, taking the planar hexagonal array formed by U·V points as an example, the arrangement method is as follows figure 2 As shown, draw the corresponding image 3 The interference power spectrum shown is shown, and on this basis, the phase ambiguity position analysis is carried out to determine whether there is a "false peak" phenomenon in this arrangement, which makes it impossible to accurately determine the number of interference and the direction of incoming waves;
[0065] (2) If there is a "false peak" phenomenon, the optimal design of the antenna array arrangement is carried out, and the two-dimensional arrangement optimization scheme based on the circular coordinate system is adopted, taking the center point of the array as the reference, and under the condition that the array size is constant Next, by adjusting the relative angle difference an...
