摘要

摘要: 该文研究了基于光波分复用网络的分布式多目标定位系统，引入混沌光电振荡器实现宽带正交波形产生，引入光波分复用网络将分布式发射和接收单元的宽带信号传输回中心站进行信号处理，基于TOA (Time Of Arrival, 到达时间)定位方法实现对多目标的精确定位。多个光载波在中心站产生，中心站的资源可支撑复杂的高精度目标定位算法，远端发射和接收单元结构简单。进行了原理验证实验，构建了2个发射机、2个接收机的实验定位系统，基于混沌光电振荡器产生了频率范围为3.1～10.6 GHz的正交混沌波形。实现了对2个目标的2维定位，最大误差为7.09 cm，并对系统架构的可重构性进行了实验验证。

Abstract: A distributed multi-target localization system based on optical Wavelength Division Multiplexing (WDM) network is demonstrated. The wideband orthogonal waveforms are generated by introducing the chaotic OptoElectronic Oscillator (OEO). The optical WDM network is introduced to transmit the wideband signals from multiple distributed transmitting and receiving units to the central station for processing, and the accurate localization of multiple targets is achieved based on the time of arrival localization method. The multiple optical carriers are generated at the central station, the complex processing to achieve the high-precision of the target localization is supported by the resources at the central station, and the remote transmitting and receiving units are simplified. Moreover, a proof of concept of the distributed multi-target localization system based on optical WDM network is obtained. The localization system comprising two transmitters and two receivers is experimentally established. The orthogonal chaotic waveforms with the frequency range of 3.1～10.6 GHz are successfully generated from the chaotic OEOs. The two-dimensional localization of two targets is realized via the maximum positioning error of 7.09 cm. Additionally, the reconfiguration of the system is experimentally verified.
