Abstract

The invention discloses a distributed phased matrix system which comprises a diversity host and a plurality of phased array antennas electrically connected with the diversity host, wherein each phased array antenna is used for monitoring a target, generating an output signal and sending the output signal to the diversity host; and the diversity host is used for receiving the output signal sent by each phased array antenna, synthesizing the received output signal sent by each phased array antenna to obtain a synthesized signal and outputting the synthesized signal. The distributed phased array provided by the invention not only obtains the characteristics of high directionality, high gain and flexible tracking of a phased array antenna array, but also has the effects of space diversity and multipath effect resistance. Multiple targets can be tracked at the same time only through one set of antenna, and compared with a parabolic antenna, the complexity and cost of the system are remarkably reduced.

Description

technical field [0001] The present application relates to the technical field of antennas, and in particular, to a distributed phased matrix system. Background technique [0002] Traditional telemetry receiving stations use parabolic antennas to track targets and receive signals, see attached figure 1 A conventional parabolic antenna is shown. The parabolic antenna only supports signal reception of a single target, is bulky, difficult to maintain, and poor in mobility. When monitoring targets in the sky, such as missiles and aircraft, the paraboloid needs to rotate with the target in the sky to achieve Continuous monitoring, so a successful and expensive mechanical electrical servo system is required to drive the motion of the parabola. Moreover, a set of parabolic antennas in the prior art can only monitor one target in the sky, but cannot monitor multiple targets. When there are multiple targets in the sky, multiple parabolic antennas are required, which is costly and m...
