多机协同控制下的航迹欺骗技术

Technology of track deception for cooperative control of multiple

摘要:

随着数据融合技术的普遍应用，雷达组网系统很容易识别对单部雷达的航迹欺骗。为了能够有效欺骗雷达组网，本文介绍了多机协同控制下的航迹欺骗技术：装备有电子对抗措施(ECM)的隐身电子战斗机(ECAV)通过采用距离延迟技术来欺骗雷达，使得雷达在其更远处进行定位，从而探测到一种被称为幻影的假目标，在经过一连串的虚假定位后便产生了虚假航迹；介绍了通过ECAV编队协作来产生具有空间、时间相关的虚假航迹的工作原理，给出了假目标的运动方程和约束条件，并提出了解决该技术问题的一些方法。经仿真验证，该技术具有一定的可行性和实用性。

Abstract:

With the extensive application of data fusion technology，it is quite easy for the network of radars to identify track deception against single radar. The stealthy Electronic Combat Air Vehicles(ECAV) equipped with Electronic Counter Measures(ECM) can deceive a radar by using range delay deception technique. This make the radar detect a fake target called phantom beyond the ECAV location. Phantom track is generated by using sequential location of phantom. The important feature of generating phantom track is its kinematic and dynamic constraints. These constraints restrict the freedom of phantom. This paper presents a technology used by the cooperative control of a team of ECAV to deceive network of radars through the generation of a space-time coherent phantom track.The equation of motion and the constraints of the phantom are given. Some approaches to solve the technical problems are described. Simulation results of the optimal control algorithm prove the feasibility and practicability of this method.
