深水探测器声引信半实物仿真技术研究

A Hardware in the Loop Simulation Research on an Explorer in Blue Water

目前对深水探测器声引信样机性能评估主要通过目标通过特性试验进行数据统计分析的方式来考核,现提出一种开环半实物仿真方法,通过模拟目标功率谱特性得到有色目标噪声信号源模型,采用带大容量FIFO缓存的数模转换技术实现信号源实时输出,并通过电信号有源衰减技术进行注入式半实物仿真取得较好效果,可以作为辅助鉴定评估其性能指标的重要方式。

The performance to explorer in the deep underwater is evaluated traditionally according to accumulating data and statistical analysis by the goal tracked characteristic experiments in the outfield. A non-feedback simulation method was proposed getting the abroad goal noise model by simulating a target power pedigree chart, generating the signal in real time by digital to analog conversion with a large capacity FIFO storage, and injecting electronic signal against an acoustic fuze in the loop simulation by attenuation with power supply. The effect is better, It could be an accessorial important manner in judging a performance on product.
