Receiver Detector

Detection of personals -Tricky problem?

Hi, i need a detector for a special project to detect people. It should consist of 2 parts, i.e. A receiver(detector) and an emitter(carried on the person)

The system must sense proximity, e.g the nearer an emitter is the faster the beeping etc or something similar, while not being affected by environment(e.g. metal detector is out, since it won't work if i sit the detector on a metal stool). GPS works fine but for reasons i can't implement it.

Does anyone have any idea? Any website link will be good to. Thanks guys!
