摘要
对目前现有舰载火控雷达零位标校的方法和技术做了简单概述,提出了一种基于差分GPS、CCD、激光经纬仪等技术相结合的零位标校新法,给出了系统硬件组成和算法原理,对系统误差影响因素做了分析。实践标明此系统可以有效的克服由于舰体的摆动而对测量精度的影响,并极大的改善了标校的灵活性与机动性。标校系统测量真值位置精度优于50 cm,相应真值角度精度优于0.05 mrad,满足舰载雷达标校精度要求。
Method and overall technology about zero position calibration of shipborne raaar were introduced in brief. A new method on zero position calibration was proposed integrated the technology of differential GPS, CCD camera , laser theodolite and so on. Hardware composition and algorithm of system were elaborated in detail, and the error of system was analyzed. It was proofed by practice that measuring accuracy was enhanced, the influence of shipbody wiming was eliminated, and system performance of flexibility and mobility were improved. And position precision of calibration was higher than 50 cm and accuracy of angle was higher than 0.05mrad. which was suit of calibration of shipborne radar.
