Abstract
Surveyance of surfaces and volumes as well as of an object located therein. A pulse transmitter (112), by means of a radiating element (116), transmits series of directive pulses (40) which are selectively received (116). The corresponding vectors as well as the variations thereof are processed in a computer (400) to determine the dimension and/or recognize the object and/or set an alarm. <IMAGE>
