Problems solved by technology

The disadvantage of this method is that the monitoring device only monitors the feeder part of the entire channel of the antenna, and fails to include the amplitude and phase characteristics of the antenna unit
The external monitoring device generally adopts the form of an external antenna unit, which usually needs to be erected in front of the antenna array with a pole, which will block the antenna array, and the monitoring accuracy is not high

Abstract

The invention relates to a monitoring device for a spherical array antenna, which includes an antenna array and a monitoring network. It is composed of patch antenna unit, microstrip feed network and metal ground connection. The monitoring network is composed of ball array, metalized via hole, strip transmission line and other connections; the advantage is that it effectively solves the problem that the existing antenna monitoring network cannot cover the outlet from the feeder To the problem of partial amplitude and phase of the antenna unit, the high-precision monitoring of the digital phased array radar antenna array is realized, and it can be widely used in the monitoring of the digital phased array radar antenna.

Description

technical field [0001] The invention relates to a radar antenna monitoring device, in particular to a monitoring device for a digital phased array radar antenna. Background technique [0002] In modern radar systems, especially in digital phased array radar systems, the channel's amplitude-phase consistency error directly affects the formation of digital beams and the angle measurement accuracy of targets, and it is necessary to monitor and correct the amplitude-phase consistency error of each channel . Therefore, in the digital phased array radar system, the antenna monitoring device plays an important role. [0003] Antenna monitoring devices can be divided into two types: internal monitoring and external monitoring. At present, the monitoring in the antenna generally adopts the form of coupling line, and the energy coupling point between the monitoring device and the antenna array is located at the outlet of the antenna unit feeder line, so as to obtain the amplitude an...
