摘要/Abstract

摘要： 由于空中超声速弹丸激波的复杂性和易被干扰性而难以捕捉，其弹目偏差测试是一大难题。为研究基于弹丸激波特性的弹目偏差测试原理和方法，在描述弹目偏差测试场景的基础上，分析激波形成机理和激波形成前后参数关系，建立弹目偏差测试模型和基于弹群激波环境简化的线性及非线性干扰模型。综合采用时间宽度测试原理进行外场试验与采用激波压力场累积效应的压力测试进行仿真反演相结合，结果表明仿真反演与工程测试相符合，为超声速运动目标声学定位和跟踪提供了一种新思路和方法。

Abstract: Since the shock wave of supersonic projectile is difficult to be captured due to its complexity and susceptible interference, the miss distance test is a difficult problem. The testing scene of miss distance is described, the formation mechanism of shock wave is analyzed, and the parameter relations before and after shock wave forming are identified. The test model of miss distance and the linear and nonlinear interference models based on simplified shock wave environment are established. The time duration test principle is used for field experiment, and the cumulative effect of pressure of shock wave field is used for simulating inversion in order to verify the accuracy and effectiveness of test methods and engineering test.
