摘　　要：提出用参数辨识确定推进剂中钾、钠杂质含量以及后燃对喷焰微波衰减影响程度的方法。用辨识的参数预估喷焰微波衰减值与实验所得结果吻合，证明了用辨识技术研究喷焰的微波衰减特性的方法是可行的。An identification technique was presented for estimating the impurity level in propellant and the properties of exhaust afterburning,which can not be measured simply by experiment.The results of microwave attenuation calculated with the values of these parameters identified accord well with the experimental results.The identification results were also analyzed.It proved that this method is feasible in the study of microwave attenuation characteristics
