Abstract
Electronic monitoring systems are being used by the criminal justice system to effect behavioral modifications of persons in pre-release prgrams, on parole, and on probation. State-of-the-art electronic monitoring systems are merely radio frequency proximity detection systems that operate over limited ranges, on the order of 45 to 70 meters. One major defect with proximity detection systems is that when the clients leave the area being monitored, there is no way to ensure that the clients are behaving properly. As a result, electronic monitoring systems are only applied to a restricted number of cases of low risk criminal offenders. There is a growing need for community-wide tracking and location technologies to increase the safety and security provided by the electronic monitoring systems, and to expand the number of cliets monitored by these systems. In this paper, a review is made of the tracking and location technologies that are currently available or under development. Also presented is a brief overview of Westinghouse's program with the National Institute of Justice. This program aims to demonstrate the practicality of one possible tracking and location technology, spread spectrum based time-of-arrival location systems, for intelligently tracking people on probation and parole.
