Embodiment Construction
[0032] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0033] Taking the five-element array (K=5) as an example, in order to explain the working principle of the look-up table method, first introduce the robust phase defuzzification method adopted by the present invention (see literature: Wang Qi. Circular array interferometer direction finding research [J]. Aerospace Electronic Countermeasures, 2009,25(5):33-35). Such as figure 2 As shown, the five array elements in the five-element array are evenly located on a circle with a radius R, and the labels are respectively 1 to 5. A Cartesian coordinate system is established with the center of the circle where the five-element array is located as the coordinate origin. The angle γ between the first array element and the X axis is 18°, and the angle ω between the array elements is 72°. Vector K is the incoming wave direction, a...
