只有角度测量的机动目标非线性预测滤波器设计

Nonlinear Predictive Filter Design for Tracking a Maneuverable Target with Angle-Only Measurement

提出了一种直接根据信息的机动目标跟踪非线性预测滤波算法，该算法不需要假定目标的机动加速度模型，而将系统的初始状态偏差和机动目标的未知加速度的综合作用结果作为系统的未知输入，利用角度的测量信息直接估计出来。通过对不同机动形式的机动目标进行仿真，结果表明文章所提出的预测滤波算法具有优良的估计性能。

：A nonlinear predictive filter algorithm is presented for tracking a maneuverable target，which is a innovation-based scheme of continuous maneuver estimation and filter．This algorithm does not necessarily rely on the assumption that the model of maneuverable target are known，and regards the effect of maneuver acceleration and the bias of the initial state as unknown inputs，which can be estimated as part of the solution．Computer simulation for various scenarios of maneuver shows the good performance of the nonlinear predictive filter．
