摘要
发动机火焰衰减是影响导弹武器系统中通信系统工作性能的重要因素。为了客观评定复杂电磁环境下武器系统工作性能,需建立准确的发动机火焰衰减模型。提出了基于测量导弹信噪比和导弹飞行姿态的发动机火焰衰减建模方法,并对模型进行了校验,成功将火焰衰减模型应用于系统性能的仿真计算与工程研制当中。
Flame attenuation of motors is the main factor affecting the work performance of communication system in the missile weapon system. A model of flame attenuation of motors should be set up precisely in order to assess the work performance of the weapon system in the complex electromagnetic environment objectively. A modeling method of flame attenuation of motors is put forward based on measured signal to noise ratio（ SNR） and flight attitude of missile. The model through the test data is checked and the flame attenuation model is applied to the simulation calculation and engineering development of the system performance successfully.
