Vibration test method for modular digital array antenna

Abstract

The invention discloses a vibration test method for a modular digital array antenna. The method includes the following steps that: S1, electrical performance testing is performed on a modular digitalarray antenna under an ideal state, a test result is recorded; S2, a three-dimensional simulated vibration testing device is established, a random one-way vibration mode and a random mixed vibration mode are set; S3, one-time transport simulation is performed on the modular digital array antenna, the modular digital array antenna is taken out and is subjected to electrical performance testing, anda test result is recorded; S4, accumulative transport simulation is performed on the modular digital array antenna, the modular digital array antenna is taken out and is subjected to electrical performance testing, and a test result is recorded; and S5, the test results are compared and analyzed, and the transport vibration condition test report of the modular digital array antenna is obtained. When the vibration test method is used, transport vibration condition simulation can be performed on the modular digital array antenna, electrical performance testing can be performed on the modular digital array antenna, and therefore, the impact of a transport process on the performance of the digital array antenna can be analyzed.

Description

technical field [0001] The invention relates to the technical field of digital array antenna testing, in particular to a vibration testing method of a modular digital array antenna. Background technique [0002] The digital array antenna is an important part of the digital array radar. It has the characteristics of multiple channels, small loss, and low sidelobes. Good digital array antenna performance is the prerequisite for the overall performance of the radar. With the improvement of R & D and production technology, modular digital array antenna equipment has appeared, which has achieved miniaturization, light weight, and low power consumption under the premise of meeting performance indicators. Existing performance tests for modular digital array antennas are carried out under ideal conditions, and digital array antennas have to go through a series of storage and transportation before they are actually put into use.

Problems solved by technology

Existing performance tests for modular digital array antennas are carried out under ideal conditions, and digital array antennas have to go through a series of storage and transportation before they are actually put into use. The environment may also be a relatively harsh weather environment. These additional factors will have an impact on the performance of the digital array antenna, and it is far from enough to simply test its performance under ideal conditions.
