This report describes the development of a radio frequency intruder detection system intended to protect high value individual resources. The work included some modifications of an already existing system as well as the development of a new instrument. The mechanism of the interaction between the single radiation wire system and the intruder has not as yet been fully understood. Therefore, the emphasis in both of the tasks was placed on the development of a data gathering research tool rather than on the production of an operational system. The original intent was to demonstrate only the feasibility of an area intrusion detection system using radiation coaxial cable, but in the continuous process of data gathering to determine the RF field characteristics of a single wire intrusion detection system, the device was also used in conjunction with other instruments, to make measurements during field operations. In parallel with these modifications another system design was considered. In the first part of this report some of the modifications of the previously constructed instrument are described. The circuit diagrams shown should be viewed in conjunction with the circuit descriptions presented in Reference 1. The rest of the report is devoted to the description of the latest instrument. Since the design of the switchable instrument did not proceed beyond the advanced planning stages no description of that system is presented.
