Description

technical field [0001] The invention relates to the fields of radar, reactance, measurement and control, communication, etc., in particular to automatic testing of digital array multi-channel acquisition excitation modules, which is used for large-scale batch testing of digital array multi-channel acquisition excitation modules. Background technique [0002] The digital array based on Digital Beam Forming (DBF) has flexible beam steering function. Compared with the traditional analog phased array, the digital array has obvious advantages in multi-target tracking, anti-interference ability, instantaneous dynamics, clutter suppression, etc., and its application prospects are wide. [0003] The T / R component is one of the key cores of a phased array and is used to achieve transmit and receive beamforming. The T / R components in the traditional analog phased array use microwave digital phase shifters to realize the channel phase shifting function, and use microwave digital atten...
