Abstract

PURPOSE:To detect the position with a simple device and facilitate the digital processing, by changing the distance between two antennas to detect the change of the phase difference between them by the microwave branching circuit. CONSTITUTION:Receiving antennas 4a and 4b are arranged apart from each other so that the distance between them can be varied. Microwave receiving signals having a phase difference are combined by magic T6 and are separated into in- phase components and antiphase components, and they are detected by detecting diodes 7a and 7b, respectively and are added by adding circuit 8. The addition output is inputted to microcomputer 11 through waveform shaping circuit 9 and pulse counter 10 to output the bearing of the position of static object 3.
