RF Indoor Intrusion Detection System

چکیده
In this paper a new RF (Radio Frequency) detection system has been descried. The proposed intrusion detection system uses one or more RF transmitters that emit RF into the space along with a well planed network of RF receivers for detection, the use of Degree of Angle (DOA) has been considered to locate intrusion. The captured RF signals are processed using developed digital space algorithms. Though in many aspects, the system works similar to that of ultrasound detector but, in this paper the immediate advantages of proposed RF Intrusion Detection System (RFIDS) with better clarity, higher frequency and higher speed of processing are highlighted. This system exhibits consistent reliable pattern of detection clearly distinguishable before and after intrusion. In such cases, even if the direct path is not obstructed, the reflected paths are definitely affected and hence the captured signals differ and can be analysed. In the proposed technique unlike the other sensory detection systems, there is no blind spot, which gives a truly contravene-less indoor intrusion detection system.

Wireless Sensing Without Sensors – An Experimental Study of Motion/Intrusion Detection using RF Irregularity
Motion and intrusion detection are often cited as Wireless Sensor Network (WSN) applications with typical configurations comprising clusters of wireless nodes equipped with motion sensors to detect human motion. Currently, WSN performance is subjected to several constraints, viz., radio irregularity and finite on-board computation/energy resources. Radio irregularity in Radio Frequency (RF) pro...
