Embodiment Construction
[0015] Below in conjunction with accompanying drawing example the present invention is described in further detail:
[0016] Combined with Figure 1, antenna element 0 is placed in the center of the antenna disk, and antenna elements 1 to 5 are placed in a uniform circular array along the antenna disk. r is the distance from the center of the antenna array element to the center of the antenna disk, and r can be taken as microwave Several to ten times the shortest wavelength of the radiation source. In order to ensure the accuracy of direction finding, the phase difference of the microwave radiation source between the antenna elements with large spacing is usually selected to solve the azimuth and elevation angle of the microwave radiation source, and this will inevitably introduce multi-valued ambiguity in the solution, which can be Arbitrarily select three antenna elements among the five antenna elements to form the first group of antenna arrays, select three antenna elements ...
