声阵列与光探测组合测试弹着点坐标的研究

在立靶密集度测试中,为构建更大的测试靶面(10m×10m),且要求测试系统具有较高的精度,在声探测阵列中增加了光探测器,组成了一种新的测量模型。该模型既具有声阵列能构成巨大测试靶面的特点,又通过引入光探测来提高测试系统的精度。推导了该模型的测量公式,并进行误差分析和仿真,得到了x坐标误差为5mm、y坐标误差为15mm的理论测试精度。

Study on Measurement of Impact Point Coordinates with the Combination of Acoustic Array and Optical Detection

In the vertical target density measuring,in order to build larger measuring target area(such as 10 m×10 m) and realize higher precision of the measuring system,an optical detector was put into the acoustic array so that a new measuring model was established.The measuring model has the features of both larger measuring target area of the acoustic array and higher precision of the optical detection.The measurement formula was deduced,and the measurement error was analyzed and simulated.The theory measurement precision of 5 mm of x coordinate error and 15 mm of y coordinate was obtained.
