引言最新靶场精密测量雷达跟踪时的角随机误差已降到0.05～0.1米位。而系统误差有时比随机误差大一个量级以上,成为跟踪误差中主要成份。然而,系统误差是确定的,按一定的规律变化,且一般可用解析式表示出来。掌握了它的变化规律或数学模型,就可对系统误差进行修正。这样,雷达的测角准确度就决定于系统误差修正后的剩余。本文从一种特定的系统误差修正方法出发,对系统误差的修正方法和提高系统误差修正精度的可能途径进行了简要的讨论。
INTRODUCTION The newest angle range precision measurement radar tracking angle error has dropped to 0.05 ~ 0.1 meters. The systematic error is sometimes more than one order of magnitude larger than the random error, becoming a major component of tracking error. However, the systematic error is definite and varies according to certain rules, and can generally be expressed analytically. Mastered its changing laws or mathematical models, the system error can be corrected. In this way, the accuracy of the radar goniometer depends on the remaining system error correction. In this paper, starting from a specific method of system error correction, a brief discussion is made on the correction methods of system errors and the possible ways to improve the accuracy of system error correction.
