Abstract

The invention relates to the technical field of phased-array antennas, and discloses a phased-array antenna wave control angle resolving method and system and a storage medium. The resolving method isshown in the description, wherein dx<10[mu]m> and dy<10[mu]m> are calculated and stored in advance, romsinx (x belongs to [0-90 degrees]) in the range of 0-90 degrees is calculated and stored in advance, and romsin[theta], romsin[psi] and romcos[psi] are directly obtained or obtained through calculation by inquiring pre-stored data. The formula is calculated through calling of a multiplier and anadder and through pre-stored calculation parameters matched with the actual angle. Only fixed-point number multiplication operation and fixed-point number addition operation need to be carried out, the requirement for operation resources of a processor is lowered, phase shift code calculation can be rapidly achieved, and the calculation time is greatly shortened.

Description

technical field [0001] The present invention relates to the technical field of phased array antennas, in particular to a phased array antenna wave control angle calculation method, a phased array antenna wave control angle calculation system, and a corresponding computer-readable storage medium. Background technique [0002] With the development and maturity of millimeter-wave active phased array technology, the advantages of no inertial scanning, high pointing accuracy, and small attenuation in the atmospheric environment make it widely used in communication, navigation, radar, guidance, etc. With the application and development of phased array antennas, the requirements for phased array antennas are getting higher and higher. Among them, the beam switching time is the key technical index of the phased array antenna, which directly determines the response time of airspace scanning and target interception, and the speed of beam switching time depends largely on the speed of ...
