Problems solved by technology

[0003] In the current software simulation, when setting the required target pattern, the angle and gain value of each point of the pattern are manually input. This method takes time to set the target pattern, and cannot intuitively express the relationship between the angle and gain and the pattern. Correspondence of waveform shape, setting efficiency is low
When setting the array element excitation, only manual input can be used, and the function of reading and loading the array data array from the file cannot be realized

Description

technical field [0001] The invention relates to an array antenna beam forming system capable of drawing a pattern, and belongs to the research field of beam forming of the antenna pattern. Background technique [0002] With the rapid development of modern microwave communication, satellite communication, and aerospace technology, today's society has higher and higher requirements for communication systems, and users have higher and higher requirements for the beam width and accuracy of antenna patterns. When synthesizing the array antenna pattern, first, according to the target pattern of the designed antenna, the beamforming algorithm is used to calculate the amplitude and phase data of the optimal solution of the shaped target pattern for each antenna unit. This data can be used as the excitation The array antenna pattern is formed into the desired target shape. An excellent algorithm becomes very important to obtain an array antenna beamforming with high efficiency and h...
