本发明实施例提供一种正交混合波束成形阵列天线，通过旋转阵列天线方向变相提高了扫描范围，由于正交天线的精准扫描范围偏向椭圆，通过预设扫描单元先发现目标，再调整阵列天线方向进行正式扫描，使得扫描范围的长边对准目标，提高了目标在扫描范围内停留的时间，提高了扫描效果。Embodiments of the present invention provide an orthogonal hybrid beamforming array antenna, which improves the scanning range by rotating the array antenna in a disguised direction. Since the precise scanning range of the orthogonal antenna deviates from an ellipse, the target is first discovered through a preset scanning unit, and then the array antenna is adjusted. The direction of the formal scanning is carried out, so that the long side of the scanning range is aligned with the target, which improves the time that the target stays in the scanning range and improves the scanning effect.
