Embodiment Construction

[0009] Establish a mathematical model for array analysis to guide theoretical design.

[0010] The present invention first uses a geometric method to divide the spherical surface into multiple polygonal planes for array arrangement, and optimizes the array arrangement efficiency in combination with the characteristics and distribution of array units. In this way, the spherical antenna array is regarded as composed of multiple planar arrays, the whole space is divided into multiple parts, and each planar array scans different subspaces. as follows figure 1 shown.

[0011] Secondly, in terms of tracking, the tracking algorithm is determined by combining with the actual motion law. In the initial scan, each surface is scanned separately, as shown in the left figure below, the scanning angle of the pentagonal array is 20.08°, and the scanning angle of the hexagonal array is 23.282°. Once the target is scanned, in order to further increase the gain, multiple area arrays that can...

Abstract

Arrangement in a spherical surface seems to be simple, but how to arrange regularly and meet the requirement of theoretical analysis and derive a directional function is not simple. On the theoretical derivation, in order to establish coordinates of each array element, array units can be distributed uniformly in any directions, but intervals of all array elements are difficult to be consistent on the spherical surface; and even if the arrangement is performed by a certain method, spherical array antennae have the problems that how to combine the array elements into wave beams and what influences occur among the array elements. On the basis of arrangement technology, the invention provides a new arrangement rule, namely a spherical polygon rule, and provides a new scanning and tracking method in the aspect of tracking.

Description

technical field [0001] As early as the late 1930s, phased array technology had appeared. In 1937, the United States first started this research work. Moreover, its research has established a relatively complete research foundation abroad as early as the 1960s. However, due to the lack of hardware development foundation and means, many achievements failed to play a role. It wasn't until recent years, especially due to demand, that people set off an upsurge of research on array antennas. [0002] The research of spherical array antenna, especially the combination with tracking algorithm has not attracted people's special attention. Although in the late 1960s, someone analyzed the use of multiple planar arrays on the hemisphere. But it was not until 2006 that someone continued to study the hemispherical polyhedron array and the optimization of the number of arrays for phased array radar. The invention is of great significance for reducing the size of the terminal, improving ...
