在无线电测向领域中，干涉仪测向具有设备复杂度低、测向精度高、响应速度快等优点，但其对天线精度要求高，而且容易受到环境干扰。数字波束形成技术可以调整波束方向、形状和增益，从而提高系统的灵敏度和抗干扰能力。通过结合干涉仪测向技术与数字波束形成技术，可以增大接收信号的信噪比，减小相位测量误差，进一步提高测向精度。

In the field of radio direction-finding, interferometric direction-finding has the advantages of low equipment complexity, high direction-finding accuracy, and fast response speed.However, it has high requirements for antenna accuracy and is easily affected by environmental interference.Digital beamforming technology can adjust the beam direction, shape and gain, thereby improving the system′s sensitivity and anti-interference ability.By combining interferometric direction-finding technology with digital beamforming technology, the signal-to-noice ratio of the recived signal can be increased, the phase measurement errors can be reduced, and the direction-finding accuracy can be further improved.
