Abstract

The invention discloses a control method for multi-beam antenna power, and relates to beam forming, based on an array antenna, of satellite navigation equipment. The control method for the multi-beam antenna power comprises the following steps: (1) calculating a multi-beam weight value, (2) calculating directivity gain of the multi-beam weight value, (3) calculating a gain direction gain parameter of a beam, (4) calculating an intensity parameter of a total beam signal, (5) calculating a control parameter of beam power, and (6) adjusting a beam weight value. Through the control method for the multi-beam antenna power, stable beam power can be guaranteed when the multi-beam is formed. In addition, the control method for the multi-beam antenna power has the advantages of being simple and practical.

Description

technical field [0001] The invention relates to the fields of satellite navigation, wireless communication, radar, sonar and the like, in particular to a power control and scheduling method in digital multi-beam formation of satellite navigation. Background technique [0002] At present, array signal processing has been applied to satellite navigation, communication, radar, sonar and other systems, and has the characteristics of flexible processing and strong anti-interference ability. The formation method is the key technology of multi-target measurement, communication and tracking. The digital multi-beam forming method is to calculate a set of weights. According to this set of weights, the array antenna can generate multiple spatially oriented beams. Multiple beams correspond to multiple targets. The power control and scheduling of multiple beams form the weights. One of the keys. [0003] For the transmitting equipment, the process of digital multi-beam forming is: firs...
