激光照射精度外场测试中，随着载机航路的变化，照射在测试靶上的激光光斑位置和尺寸是不同的。针对测试靶参数选取问题，提出了一种估算方法，建立了测试靶参数的估算模型，满足了不同载机航路的测试靶参数计算需要，为合理设置测试靶提供了一种实用方法。试验结果表明，用该方法设置测试靶倾角、尺寸及十字线位置，可以测量全部激光光斑，为准确测量激光照射精度提供了依据。

In precision test of laser irradiation,the position and size of laser spot on the test target will change with the aircraft route.To properly set the target,parameter estimation method is proposed.The estimation model of test target parameters is built,and calculation requirement of test target parameters for different aircraft routes is met,which pro-vides a feasible way for the target settings.Test results indicate that laser spot can be measured totally by setting the proper parameters,such as oblique angle,size and cross centre of the target board,which provide a reference for meas-uring laser radiation sensitivity accurately.
