引言使用具有数据汇合的多传感器概念已广泛用于警戒系统。应用多传感器的一个主要目的是改进诸如可靠性和反应速度的系统性能。对于正在研制的要求大面积覆盖和能对付大量目标的警戒系统来说,应采用多传感器。在这样的系统中,要把全部观察结果由传感器送到中心处理机,供数据处理用。这就需要不可能得到的大的通信带宽。这样,由于通信信道的限制,在许多情况下提出了具有数据汇合中心的分布式信号处理。在分布式检测系统中,每个传感器内对信号进行预处理,然后将分别获得的结果送到数据汇合中心,在汇合中心得到希望的总结果。本文将研究具有数据汇合的分布式恒虚警率检测。
Introduction The concept of using multisensors with data merging has been widely used in alert systems. One of the main purposes of applying multisensors is to improve system performance such as reliability and speed of response. Multi-sensors should be used for alert systems being developed that require large area coverage and can handle a large number of targets. In such a system, all the observations should be sent to the central processor by the sensor for data processing purposes. This requires a large communication bandwidth that can not be obtained. Thus, distributed signal processing with data convergence centers has been proposed in many cases due to the limitations of communication channels. In a distributed inspection system, the signals are preprocessed in each sensor and the results obtained are then sent to the data fusion center where the desired aggregate result is obtained. In this paper, we will study distributed CFAR detection with data convergence.
