摘要
为了利用主动雷达的现有能力,提高海面物体的定位精度,同时使系统的组成尽可能简单,提出了基于测距交会的海面物体高精度定位方法。首先基于海面物体零高程假设,建立了基于测距交会的海面物体高精度定位模型,利用主动雷达的高精度测距信息解算出海面物体的位置,然后根据定位模型推导出精度表达式,并对定位精度及其影响因素进行了仿真分析,结果显示,利用测距交会定位方法可以显著提升目标定位精度,且对精度影响最大的是主动雷达的测距误差,其次是平台位置误差,影响最小的是海浪高度误差。
In order to make use of the existing ability of active radar, improve the positioning accuracy of sea surface objects, and make the composition of the positioning system as simple as possible, a high-precision positioning method of sea surface objects based on ranging intersection is proposed. Firstly, based on the assumption of zero elevation of sea surface object, a high-precision positioning model of sea surface objects based on ranging intersection was established, and the position of sea surface objects was calculated by using the high-precision ranging information of active radar. Then, the precision expressing was derived according to the positioning model. Finally, the positioning accuracy and its influencing factors were simulated. The results show that the ranging rendezvous positioning method of dual active radars can significantly improve the target positioning accuracy, and the biggest influence is the radar ranging error, followed by the platform positioning error, and the smallest is the wave height error.
