摘　　要：在目标匀速直线运动的假设下 ,通常的运动目标参数估计方法 ,需要得到航迹上的 2个有效测量点来建立航迹初值。该文提出了一种新的基于运动目标多角度信息的参数估计方法 ,在提高激光动态回波率受限制的前提下 ,从得到第 1个目标距离信息开始即可建立航迹初值 ,从而可以缩短火控系统的反应时间。由于利用光学仪器可以被动地测量目标的多角度值 ,并且理论上只需获得 1个主动激光回波 。It is supposed that the target's velocity be invariable in a line, initial values of the trajectory can be obtained from two valid points of the trajectory at least by the usual methods. A new parameter estimation method based on the multi angle information for a flying object is presented. Using the method, initial values of the trajectory can be gotten with only one distance under the limitation of laser dynamic echo wave ratio, therefore the response time of the fire control system can be shortened. The multi angle values can be passively measured by optical instruments, and only one active laser echo ought to be obtained in theory, then the measure instrument will be concealed to a certain extent.
