Description

technical field [0001] The invention relates to a Ka-band standardized four-channel transmitting assembly, which belongs to the technical field of phased array radars. Background technique [0002] Phased array radar uses a large number of antenna elements with independent amplitude and phase control to form an antenna array. By controlling the amplitude and phase of each array element, it forms beams with specific directions for each unit, and finally synthesizes the main beam. Due to the advantages of multi-target tracking, airspace filtering, multi-beam fast scanning, flexible pointing, and high reliability, phased array radar has become the main development direction in the field of radar detection today. The transmitting component located at the front end of the phased array radar is one of its core components. It is the main control part of the antenna radiation amplitude and phase. The performance of the phased array system plays a decisive role and is the main cost ...
