Study on reliability growth of space borne SAR T/R module

摘要

Aiming at the disparity of reliability and lifetime between China made space borne SAR T/R module and overseas advanced product, reliability growth necessity is discussed in this paper. Procedure of reliability growth study, several important experiments, and difficulties encountered in the experiments along with solutions are introduced. Experiment results of this reliability growth study are revealed as follow: design lifetime of space borne SAR T/R module is improved evidently, simultaneously reliability of T/R module at the end of rated lifetime is expected higher than before, the cycle and funds of developing a new type of T/R module will be decreased greatly, etc.
