However, those research was based on single target ship and there was little research on multi-ship radar plotting assessment system.

但目前的研究大部分是基于单物标船的研究，对于多物标雷达标绘评估系统的研究还很少涉及。

First of all, the dissertation reasons out the general mathematic models of radar plotting by means of the plane analytic geometry, and establishes the assessment factors of the system.

论文首先推导出雷达标绘的通用数学模型，并进一步确立系统的评估要素。
