3R定位系统在最佳目标—雷达站几何下的误差传播特性

求解3R定位系统的最佳目标一雷达站几何是CW雷达定位体制研究中的关键问题之一。这种最佳几何是3个雷达天线位于正三角形的顶点，3个天线波束在空间正交。给出了利用最优化方法求解这种最佳几何的目标函数，并给出了3R定位体制的普适性误差椭球的二次曲面方程。研究结果表明，在上述最佳目标一雷达站几何下，椭球形误差二次曲面变为圆球形误差二次曲面。

Error Propagation Property of 3 R Positioning System under Optimum Target-Radar Stations Geometry

Determination of the optimum target-radar stations geometry is one of the important problems in the study of the positioning system CW radars. In an optimum geometry,three radar antennas are at the tips of a regular triangle and are orthogonal with each other in space. This paper uses an optimized method to give the target function that determines the optimum geometry. The equation of second order curved surface forming an error ellipsoid is also given. Results of study show that the error ellipsoid becomes an error ball.
