Abstract
The obstacle sensor operating by collimation and focusing of the emitted wave comprising an IMPACT or a GUNN diode (9) has, in a coaxial sequential order, a cavity (8) of generation and selection of the waves emitted by the generating diode (9), a polarise (12), a passive intermediate reflector and at least an optical apparatus (12) of focusing and concentration of the waves emitted along the axis of an antenna (5). The optical apparatus constitutes the generation whole of a beam of concentrated, unipolar coherent waves of the desired frequency and the maximum intensity and power. The microwaves emitted by antenna (5) in the omnipolar direction are focused and concentrated in one only coherent and phased beam. The unidirectional reflected wave or echo, obtained from sensing a still or moving obstacle, is sensed by the same system, and analysed and quantified with respect to the typical behaviour of the diode used as a microwave generator.
