<p>PURPOSE:To provide an FM radar module which allows reduction of the number of parts used and which is embodied in a small size and at a low cost. CONSTITUTION:Signal reception and transmission are made with one antenna 12, which is connected with an FM signal generator 11 through a waveguide path, for example a waveguide tube 13. In this waveguide path, a diode such as a Schottky barrier diode SBD is installed to constitute a mixer 14.</p> |
