摘要
针对移动目标的定位,提出了一种新的定位系统,它由少量低成本红外发射器和接收器构成的传感器网络构成。红外发射器装置的处理单元产生混合和放大的红外模式和载波,然后再由一个或多个红外发射二极管发射。红外接收器装置采用特定载波频率调制的红外信号,通过积分器阻隔载波,由接收器处理单元识别出纯红外模式信号,并通过应用Turbo解码算法,以最小化估计过程中瞬时噪声造成突发差错的影响,从而实现目标的精确位置和方位估计。还给出了系统的位置估计拓扑,并进一步分析了定位算法原理及性能指标。实验结果表明,相比于其他定位系统,本文提出的定位系统不仅具有低的复杂性和成本,而且具有稳定可靠的较小的定位误差。
Aiming at the positioning of moving target,a new positioning system is proposed,which consists of a sensor network being made up of a few low-cost infrared transmitters and receivers.The processing unit of the infrared emitter device generates mixed and amplified infrared modes and carriers,which are then emitted by one or more infrared emitting diodes.The infrared receiver device adopts the infrared signals modulated at specific carrier frequency.Through the integrator rejecting carrier,the pure infrared pattern signal is recognized by the processing unit of the receiver,and through the application of Turbo decoding algorithm,the effect of burst errors caused by instantaneous noise in the estimation process is minimized so as to achieve precise location and orientation estimation of the target.The location estimation topology of the system is also given,and the principle and performance index of the positioning algorithm are further analyzed.The experimental results show that,compared with other positioning systems,the proposed positioning system not only has low complexity and cost,but also has stable and reliable smaller positioning errors.
