本文给出了扫描雷达估算角度(通常是方位角)误差的标准偏差的闭式表达式。该公式适用于斯沃林(Swerling)误差下限和使用脉冲——脉冲双极滤波器所产生的误差。适用于非起伏目标和斯沃林Ⅱ目标,对所有的信杂比均成立。与文献中图示结果的比较表明,使用此公式所获得的平均偏差小于4％。
This paper presents a closed-form expression for the standard deviation of the error of the scanning radar’s estimation of angle (usually azimuth). The formula applies to the Swerling error floor and the error generated using a pulse-pulse bipolar filter. For non-undulated targets and Svelrin II targets, all of the signal-to-noise ratio holds. A comparison with the graphical results in the literature shows that the average deviation obtained using this formula is less than 4%.
