偏移对圆概率误差估计的影响AI 解读

Two estimates for the Circular Probable Error (CEP) are studied to determine their effectiveness when the aim point is shifted from the target center to another point. It is assumed that the distribution of points is bivariate circular normal, with mean value (or aim point) at (m 1, m 2) and variances σ x 2 = σ y 2 = σ2. Both estimates are unbiased and asymptotically efficient when the aim point is at (0, 0). When the aim point is shifted, only one of the estimates is…
