摘　　要：舰艇编队作战时,交叉定位是其主要抗干扰作战方式之一。而交叉定位能力是否有效取决于其定位精度是否满足武器系统的要求。交叉定位精度与很多因素都有关联,本文主要分析舰载雷达的跟踪性能对交叉定位精度的影响,为后续如何开展交叉定位试验及如何提高交叉定位精度具有指导意义。本文建立了动平台下三坐标交叉定位模型,结合误差传递函数,建立了交叉定位精度误差模型,并仿真分析了双雷达跟踪性能对交叉定位精度的影响。In naval formation combat,cross-positioning is one of the main anti-jamming methods.The effectiveness of cross-positioning capability depends on whether its positioning accuracy meets the requirements of weapon system.The accuracy of cross-positioning is related to many factors,among which the influence of the tracking performance of shipborne radar on cross-positioning accuracy was analyzed in this paper.It is of great significance on the way to carry out cross-positioning tests and to improve the accuracy of cross-positioning.In this paper,a 3-D cross-positioning model was established on a moving platform;combining with the error transfer function,a cross-positioning accuracy error model is established;and the dual radar tracking performance on cross-positioning accuracy was simulated and analyzed.
