Abstract

The invention discloses an environmental screening method of an array antenna. The environmental screening method of the array antenna mainly comprises the following steps that under the standard atmospheric pressure condition, initial function detection is carried out on screened products according to items and requirements specified by product technical conditions, detection data is recorded, and environmental stress screening is not carried out on products which are unqualified in detection; meanwhile the screened products with qualified function detection are subjected to function detection through temperature circulation and vibration circulation ; and then the final function detection is carried out under the standard atmospheric condition. Circulation is carried out for 10 times ina temperature change box, and stress test is carried out for 5 min in the environment with the temperature being +85 DEG C to -55 DEG C and the temperature change rate being 5 DEG C / min and in vibration environment to eliminate defective parts, components and process defects in products and prevent early failure.
