Abstract
A radio apparatus has a detector for detecting the electric field intensity of a test signal received from the other radio apparatus. The detector produces a mean value of the field intensity detected at a predetermined interval and outputs the resulting latest field intensity level signal to a memory circuit. Further, the detector sequentially compares the latest field intensity level signal with a plurality of intensity level signals stored in the memory circuit and thereby delivers a decision signal to a display. In response, the display displays a detailed positional relation between the two radio apparatuses.
