PCT No. PCT/EP97/02156 Sec. 371 Date Nov. 16, 1998 Sec. 102(e) Date Nov. 16, 1998 PCT Filed Apr. 25, 1997 PCT Pub. No. WO97/43663 PCT Pub. Date Nov. 20, 1997The measurement apparatus (1) delivers both a raw measurement d(i) of the distance and a raw measurement v(i) of the relative speed of said object with respect to the apparatus (1). According to the invention, said speed measurement v(i) is integrated over a predetermined sliding time interval, the difference of the raw distance measurement d(i) and of the integral d'(i) of the speed is formed, a mean value (Cdif) of said difference is calculated over said time interval and the calculated mean (Copt) is added to the integral d'(i) of the speed to form a filtered measurement (dfilt) of the object/measurement apparatus distance.
