摘　　要：传统信息场参数测量方式只能测量制导始端和末端的信息场参数,无法测量制导过程中信息场参数,不能全面对制导过程中制导仪性能进行准确评估。为解决传统测量方式存在的问题,采用大口径变焦平行光管与精密光栅尺测控技术实现信息场的制导距离测量,通过专用光纤靶标与P IN阵列探测器接收信息场,根据已建立的数学模型对信号处理,从而得到制导过程中信息场参数。实践验证测量系统的指令测试精度达到0.01单位指令,照度测量精度为5%,光轴一致性精度为4.89″。Since traditional measurement can only measure the parameters of information field at the beginning stage and terminal stage,complete information field parameters during whole guiding process is not available and the missile guidance performance can not be accurately evaluated.To solve this problem,the guiding distance measurement of the information field was realized by using large aperture zooming collimator and precision grating ruler.The information field was detected by optical fiber target and PIN detector array.The signal was processed according to the existing mathematical model and the information field parameters during guiding process were obtained.Results indicate that the test accuracy of command test reaches 0.01 unit command,the accuracy of irradiance measurement reaches 5% and the bore-sight accuracy reaches to 4.89″.
