基于双基地雷达探测的跟踪优化建模仿真研究

Modeling and Simulation of Track Optimization Based on Bistatic Radars Detection

在雷达探测性能的研究中,双基地雷达具有隐蔽性能好、抗干扰能力强等特点。但由于当前的双基地雷达目标跟踪模型大多采用发射站和接收站在同一坐标轴上的坐标系,不具有通用性和扩展性。为解决上述问题,提出一种采用通用直角坐标系的双基地雷达跟踪模型,选取坐标轴可任意设置的通用直角坐标系。在此基础上推导了目标直角坐标与雷达可直接测量的目标参数之间的转换关系,并对量测方程进行线性化,实现了对双基地雷达跟踪模型的优化。计算机仿真和实测处理验证了该跟踪模型的正确性和有效性。

Bistatic radars have many advantages, such as good concealment performance and strong anti -jam- ming capability. In most of the published literatures, target tracking models for bistatic radars adopt the coordinates in which the transmitting station and the receiving station locate in the same axis, which makes the models have no u- niversality and expandability. In order to solve this problem, a tracking model of bistatic radars is put forward based on universal Cartesian coordinates in which axes can be set arbitrarily. On the basis of the model, a conversion rela- tion is derived between the target coordinates and the directly measured target parameters, the measurement equation is linearized, and the optimization of bistatic radar tracking model is realized. Finally, computer simulation and field - data processing prove the correctness and effectiveness of this tracking model.
