多目标检测系统的设计与仿真

针对多个设备或设备的多个部件由于分布范围大,设备应用环境复杂等原因,导致无法对其进行近距离控制和测量,对地面多个设备的检测设计了一种多目标检测控制系统。该设计采用基于码分多址的直序扩频技术对目标发射的信号进行区分,在信号处理部分采用改进自适应盲多用户恒模算法对其检测分离。仿真结果表明,该设计实现了对多个目标的检测与控制,并能恢复出测量信号波形,具有较高的抗噪性能。

The Design and Simulation of Multi-target Detection System

For a number of multiple devices or device components,because the reasons of wide distribution,complex application environment and so on,they can not be closely controlled and measured. Therefore,in this paper the multi-arget detection and control system is designed for the detection of multiple targets on the ground. Direct sequence spread spectrum technology is used to make a distinguish between different targets of signal. And the improved adaptive blind multi-user constant modulus algorithm is used for detection and separation of different users in signal processing section. The simulation results show that the design can achieve the multiple target detection and control,restore a measure signal waveforms and has a high anti-noise performance.
