组网雷达快速标校优化航路规划方法

针对现有雷达动态标校方法无法实现一条航路完成组网雷达快速高精度标校问题，提出了一种基于斜距极差的组网雷达快速标校优化航路规划方法。该方法通过计算各雷达对航路斜距极差，设计一条以总斜距极差最大准则与规避各雷达近空盲区为双判据的标校优化航路，实现组网后多站同时标校。对系统误差建模，通过对系统误差估计算法分析，得到了影响系统误差估计的主要因素为斜距极差的结论，并基于此提出了该优化航路规划方法。仿真实验结果表明，基于优化航路得到的误差参数估计精度明显优于对比航路，对斜距偏差和斜距误差增益的估计偏差百分比分别为2.7%和5%，验证了所提方法的有效性和优越性。

Method of Optimizing Route Planning for Rapid Calibration of Netted Radar

In order to solve the problem that the existing radar dynamic calibration methods can not achieve the rapid and high-precision calibration of netted radars in one route, an optimized route planning method for rapid calibration of netted radars based on the range of slant distance is proposed. This method designs a calibration optimization route based on the double criteria of maximum principle of the total range of slant distance and avoiding the close-range blind zone of each radar by calculating the range of slant distance of each radar to the route, and realizes the simultaneous calibration of multiple stations after networking. The systematic error is modelled in this paper, and by the analysis of the systematic error estimation algorithm, it is concluded that the principal factor affecting the systematic error estimation is the range of slant distance. Based on this conclusion, an optimal route planning method is proposed. The results of the simulation experiments show that the accuracy of error parameter estimation based on the optimized route is obviously better than that of the contrastive routes, and the estimated deviation percentages of the slant distance deviation and the slant distance error gain are 2.7% and 5% respectively, which verifies the effectiveness and superiority of the proposed method.
