基于RTK的毫米波导引头对动目标性能评估方法
|
摘要
针对毫米波导引头对动目标的性能评估问题,基于定位精度高、可实现全天候作业的载波相位差分技术,提出了一种有效的毫米波导引头对动目标的性能测试方法。在计算参数前,利用机载发控装置实现载机端GPS接收机装置和目标端GPS接收机装置之间的时间同步。同时,该方法利用机载端和目标端GPS接收装置获得的位置信息推导毫米波导引头的相关参数,通过比较计算得到的相关参数和导引头的输出,评估毫米波导引头对动目标的性能。实测挂飞数据验证了所提方法的有效性。
Focusing on performance assessment of the millimeter wave( MMW) seeker towards moving targets,an effective testing approach is proposed by using the real-time kinematic( RTK) technology,which has the advantages of high-precision orientation and working ability under all climates. Prior to parameter calculation,time synchronization is conducted between the global positioning system( GPS) receivers of the platform and the target utilizing the electropult system. Parameters of the seeker are calculated based on the obtained orientation information. The assessment results are drawn by comparing the deduced results with the outputs from the MMW seeker. The effectiveness of the proposed method has been validated by the mooring test-fly experiments towards moving targets.
