一种尺度目标模拟器的模拟逼真度分析

从潜艇回波特性研究一般性结论和鱼雷常用目标识别方法入手,以一种单收多发尺度目标模拟器为例,分析了尺度目标模拟器的工程模型及工程实现中的关键参数,仿真结果表明,该模拟器在多亮点结构回波的多普勒频移模拟、时延模拟和目标强度模拟等方面都存在一定的不足,还有较大的提升空间,该研究为尺度目标模拟技术的进一步优化提供了参考。

Fidelity Analysis of a Scale Target Simulator

On the basis of the common conclusion of echo characteristics of a submarine and the general recognition method for a torpedo, we take single-receiving multi-transmitting scale target simulator for example to analyze the en- gineering model of a scale target simulator and the key parameter in engineering implementation. Simulation results show that this simulator has insufficiencies in Doppler frequency shift, time delay, and target strength of multi-highlight structure echo, which infers a large space for improvement. This study may provide a reference for further optimization of the scale target simulation technology.
