Abstract


A very wide range of signal monitoring applications using a specific carrier , check the consistency of the transmitted signal , to find and lock the position of the unknown or illegal transmitter , it plays an important role . Traditional signal monitoring method is mainly dependent on the high-performance spectrum analyzer and is often used as a stand-alone system digital converter . Sensor network as an access to information and treatment , in the areas of civil , commercial and military shows broad application prospects . In this paper, a wireless RF sensor network - based signal monitoring method , it uses a low-cost receiver collaborative network monitoring large areas within the geographical area of wireless spectrum by these receivers can improve the efficiency of the signal monitoring , but also to positioning transmitter geographic . In engineering , so that high-density and low-cost RF sensor system to improve the received signal gain is very meaningful . In this paper, the traditional signal monitoring system and its key technologies , signal monitoring system architecture based RF sensor network . The system is controlled by a central server and a plurality of distributed receiver (also called RF sensor ) . By the respective receivers , the system coverage area of ??the radio conditions of the network real - time monitoring , and the target signal for subsequent processing . This article focuses on the key technology of the basic structure of the RF sensor and sensor networks . Including sensor network synchronization radio signal localization algorithm (TDOA, Time Difference Of Arrival), signal recognition technology . Signal monitoring and positioning technology based on the actual deployment of the RF sensor network is ideal experimental results . Experimental data , analysis of the characteristics of the positioning of narrowband signals and broadband signals , take the correlation detection method , enhance the small signal monitoring capabilities , and improve the ability to intercept . The results of the intended purpose , the positioning of the transmitting station . The results show that using multiple RF sensor in a collaborative manner , can be effective on the detection of small signals .
